sport. Crime, d' ye see, is a personal and individual business. One doesn't make up a parti carré for a murder as one does for a bridge game. Markham, old dear, don't let this romantic criminological idea lead you astray. And don't scrutinize the figurative footprints in the snow too closely. They'll confuse you most horribly you're far too trustin' and literal for this wicked world. I warn you that no clever criminal is going to leave his own footprints for your tape-measure and calipers."

He sighed deeply, and gave Markham a look of bantering commiseration.

"And have you paused to consider that your first case may even be devoid of footprints? ... Alas! What, then, will you do?"

"I could overcome that difficulty by taking you along with me," suggested Markham, with a touch of irony. "How would you like to accompany me on the next important case that breaks?"

"I am ravished by the idea," said Vance.

Two days later the front pages of our metropolitan press carried glaring headlines telling of the murder of Margaret Odell.

THE MURDER

(Tuesday, September 11; 8.30 a. m.) It was barely half past eight on that momentous morning of September the 11th when Markham brought word to us of the event.

I was living temporarily with Vance at his home in East 38th Street-a large remodelled apartment occupying the two top floors of a beautiful mansion. For several years I had been Vance's personal legal representative and adviser, having resigned from my father's law firm of Van Dine, Davis and Van Dine to devote myself to his needs and interests. His affairs were by no means voluminous, but his personal finances, together with his numerous purchases of paintings and objets d'art, occupied my full time without burdening me. This monetary and legal stewardship was eminently congenial to my tastes; and my friendship with Vance, which had dated from our undergraduate days at Harvard, supplied the social and

human element in an arrangement which otherwise might easily have degenerated into one of mere drab routine.

On this particular morning I had risen early and was working in the library when Currie, Vance's valet and majordomo, announced Markham's presence in the living-room. I was considerably astonished at this early-morning visit, for Markham well knew that Vance, who rarely rose before noon, resented any intrusion upon his matutinal slumbers. And in that moment I received the curious impression that something unusual and portentous was toward.

I found Markham pacing restlessly up and down, his hat and gloves thrown carelessly on the centre-table. As I entered he halted and looked at me with harassed eyes. He was a moderately tall man, clean-shaven, gray-haired, and firmly set up. His appearance was distinguished, and his manner courteous and kindly. But beneath his gracious exterior there was an aggressive sternness, an indomitable, grim strength, that gave one the sense of dogged efficiency and untiring capability.

"Good morning, Van," he greeted me, with impatient perfunctoriness. "There's been another half-world murder-the worst and ugliest thus far. . . ." He hesitated, and regarded me searchingly. "You recall my chat with Vance at the club the other night? There was something damned prophetic in his remarks. And you remember I half promised to take him along on the next important. case. Well, the case has broken-with a vengeance. Margaret Odell, whom they called the Canary, has been strangled in her apartment; and from what I just got over the phone, it looks like another night-club affair. I'm headed for the Odell apartment now... What about rousing out the sybarite?"

"By all means," I agreed, with an alacrity which, I fear, was in large measure prompted by purely selfish motives. The Canary! If one had sought the city over for a victim whose murder would stir up excitement, there could have been but few selections better calculated to produce this result.

Hastening to the door, I summoned Currie, and told him to call Vance at once.

"I'm afraid, sir-" began Currie, politely hesitant.

"Calm your fears," cut in Markham. "I'll take all responsibility for waking him at this indecent hour."

Currie sensed an emergency and departed.

A minute or two later Vance, in an elaborately embroidered silk kimono and sandals, appeared at the living-room door.

"My word!" he greeted us, in mild astonishment, glancing at the clock. "Haven't you chaps gone to bed yet?" He strolled to the mantel, and selected a gold-tipped Régie cigarette from a small Florentine humidor.

Markham's eyes narrowed: he was in no mood for levity.

"The Canary has been murdered," I blurted out.

Vance held his wax vesta poised, and gave me a look of indolent inquisitiveness. "Whose canary?"

"Margaret Odell was found strangled this morning," amended Markham brusquely. "Even you, wrapped in your scented cotton-wool, have heard of her. And you can realize the significance of the crime. I'm personally going to look for those footprints in the snow; and if you want to come along, as you intimated the other night, you'll have to get a move on." Vance crushed out his cigarette. "Margaret Odell, eh?-Broadway's blonde Aspasia or was it Phryne who had the coiffure d'or? . . . Most distressin'!" Despite his offhand manner, I could see he was deeply interested. "The base enemies of law and order are determined to chivvy you most horribly, aren't they, old dear? Deuced inconsiderate of 'em! . . . Excuse me while I seek habiliments suitable to the occasion."

He disappeared into his bedroom, while Markham took out a large cigar and resolutely prepared it for smoking, and I returned to the library to put away the papers on which I had been working.

In less than ten minutes Vance reappeared, dressed for the street.

"Bien, mon vieux," he announced gaily, as Currie handed him his hat and gloves and a malacca cane. "Allons-y!"

We rode up-town along Madison AveVOL. LXXXI.—39

nue, turned into Central Park, and came out by the West 72d Street entrance. Margaret Odell's apartment was at 184 West 71st Street, near Broadway; and as we drew up to the curb, it was necessary for the patrolman on duty to make a passageway for us through the crowd that had already gathered as a result of the arrival of the police.

Feathergill, an assistant District Attorney, was waiting in the main hall for his Chief's arrival.

"It's too bad, sir," he lamented. "A rotten show all round. And just at this time! . . ." He shrugged his shoulders discouragingly.

"It may collapse quickly," said Markham, shaking the other's hand. "How are things going? Sergeant Heath phoned me right after you called, and said that, at first glance, the case looked a bit stubborn."

"Stubborn?" repeated repeated Feathergill lugubriously. "It's downright impervious. Heath is spinning round like a turbine. He was called off the Boyle case, by the way, to devote his talents to this new shocker. Inspector Moran arrived ten minutes ago, and gave him the official imprimatur."

"Well, Heath's a good man," declared Markham. "We'll work it out. . . . Which is the apartment?"

Feathergill led the way to a door at the rear of the main hall.

"Here you are, sir," he announced. "I'll be running along now. I need sleep Good luck!" And he was gone.

It will be necessary to give a brief description of the house and its interior arrangement, for the somewhat peculiar structure of the building played a vital part in the seemingly insoluble problem posed by the murder.

The house, which was a four-story stone structure originally built as a residence, had been remodelled, both inside and outside, to meet the requirements of an exclusive individual apartment dwelling. There were, I believe, three or four separate suites on each floor; but the quarters up-stairs need not concern us. The main floor was the scene of the crime, and here there were three apartments and a dentist's offices.

The main entrance to the building was

the stairway leading to the floors above; and directly beyond the stairway, also on the right, was a small reception-room with a wide archway instead of a door. Directly opposite to the stairway, in a small recess, stood the telephone switchboard. There was no elevator in the house.

Another important feature of this ground-floor plan was a small passageway at the rear of the main hall and at right angles to it, which led past the front walls of the Odell apartment to a door opening on a court at the west side of the building. This court was connected with the street by an alley four feet wide.

In the accompanying diagram this arrangement of the ground floor can be easily visualized, and I suggest that the reader fix it in his mind; for I doubt if

ever before so simple and obvious an architectural design played such an important part in a criminal mystery. By its very simplicity and almost conventional familiarity—indeed, by its total lack of any puzzling complications-it proved so baffling to the investigators that the case threatened, for many days, to remain forever insoluble.

As Markham entered the Odell apartment that morning Sergeant Ernest Heath came forward at once and extended his hand. A look of relief passed over his broad, pugnacious features; and it was obvious that the animosity and rivalry which always exist between the Detective Division and the District Attorney's office during the investigation of any criminal case had no place in his attitude on this occasion.

"I'm glad you've come, sir," he said; and meant it.

He then turned to Vance with a cordial smile, and held out his hand.*

"So the amachoor sleuth is with us again!" His tone held a friendly banter.

"Oh, quite," murmured Vance. "How's your induction coil working this beautiful September morning, Sergeant?"

"I'd hate to tell you!" Then Heath's face grew suddenly grave, and he turned to Markham. "It's a raw Ideal, sir. Why in hell couldn't they

have picked some one besides the Canary for their dirty work? There's plenty of Janes on Broadway who coulda faded from the picture without causing a second alarm; but they gotta go and bump off the Queen of Sheba!"

As he spoke, William A. Moran, the commanding officer of the Detective Bureau, came into the little foyer and performed the usual hand-shaking ceremony. Though he had met Vance and me but once before, and then casually, he remembered us both and addressed us courteously by name.

"Your arrival," he said to Markham, in a well-bred, modulated voice, "is very welcome. Sergeant Heath will give you what preliminary information you want.

*Heath had become acquainted with Vance during the

investigation of the Benson murder case two months previ

ously.

glass doors opening into the main room beyond. There was no other entrance to the apartment, and the bedroom could be reached only through the archway from the living-room.

There was a large davenport, covered with brocaded silk, in front of the fireplace in the left-hand wall of the living-room, with a long narrow library-table of inlaid rosewood extending along its back. On the opposite wall, between the foyer and the archway into the bedroom, hung a triplicate Marie Antoinette mirror, beneath which stood a mahogany gatelegged table. On the far side of the archway, near the large oriel window, was a baby grand Steinway piano with a beautifully designed and decorated case of Louis-Seize ornamentation. In the corner to the right of the fireplace was a spindle

legged escritoire and a square handpainted waste-paper basket of vellum. To the left of the fireplace stood one of the loveliest Boule cabinets I have ever seen. Several excellent reproductions of Boucher, Fragonard, and Watteau hung about the walls. The bedroom contained a chest of drawers, a dressing-table, and several gold-leaf chairs. The whole apartment seemed eminently in keeping with the Canary's fragile and evanescent personality.

As we stepped from the little foyer into the living-room and stood for a moment looking about, a scene bordering on wreckage met our eyes. The rooms had apparently been ransacked by some one in a frenzy of haste, and the disorder of the place was appalling.

'They didn't exactly do the job in dainty fashion," remarked Inspector Moran.

"I suppose we oughta be grateful they didn't blow the joint up with dynamite,' returned Heath acridly.

But it was not the general disorder that most attracted us. Our gaze was almost immediately drawn and held by the body of the dead girl, which rested in an unnatural, semirecumbent attitude in the corner of the davenport nearest to where we stood. Her head was turned backward, as if by force, over the silken tufted upholstery; and her hair had come unfastened and lay beneath her head and over her bare shoulder like a frozen cataract of liquid gold. Her face, in violent death, was distorted and unlovely. Her skin was discolored; her eyes were staring; her mouth was open, and her lips were drawn back. Her neck, on either side of the thyroid cartilage, showed ugly dark bruises. She was dressed in a flimsy evening gown of black Chantilly lace over cream-colored chiffon, and across the arm of the davenport had been thrown an evening cape of cloth-of-gold trimmed with ermine.

There were evidences of her ineffectual struggle with the person who had strangled her. Besides the dishevelled condition of her hair, one of the shoulder-straps of her gown had been severed, and there was a long rent in the fine lace across her breast. A small corsage of artificial orchids had been torn from her bodice, and

lay crumpled in her lap. One satin slipper had fallen off, and her right knee was twisted inward on the seat of the davenport, as if she had sought to lift herself out of the suffocating clutches of her antagonist. Her fingers were still flexed, no doubt as they had been at the moment of her capitulation with death, when she had relinquished her grip upon the murderer's wrists.

The spell of horror cast over us by the sight of the tortured body was broken by the matter-of-fact tones of Heath.

"You see, Mr. Markham, she was evidently sitting in the corner of this settee when she was grabbed suddenly from behind."

Markham nodded. "It must have taken a pretty strong man to strangle her so easily."

"I'll say!" agreed Heath. He bent over and pointed to the girl's fingers, on which showed several abrasions. "They stripped her rings off, too; and they didn't go about it gentle, either." Then he indicated a segment of fine platinum chain, set with tiny pearls, which hung over one of her shoulders. "And they grabbed whatever it was hanging round her neck, and broke the chain doing it. They weren't overlooking anything, or losing any time. . . . A swell, gentlemanly job. Nice and refined."

"Where's the Medical Examiner?" asked Markham.

"He's coming," Heath told him. "You can't get Doc Doremus to go anywheres without his breakfast."

"He may find something else—something that doesn't show."

"There's plenty showing for me," declared Heath. "Look at this apartment. It wouldn't be much worse if a Kansas cyclone had struck it."

We turned from the depressing spectacle of the dead girl and moved toward the centre of the room.

"Be careful not to touch anything, Mr. Markham," warned Heath. "I've sent for the finger-print experts-they'll be here any minute now."

Vance looked up in mock astonishment. "Finger-prints? You don't say really! How delightful!-Imagine a johnnie in this enlightened day leaving his finger-prints for you to find.'

"All crooks aren't clever, Mr. Vance," declared Heath combatively.

"Oh, dear, no! They'd never be apprehended if they were. But, after all, Sergeant, even an authentic finger-print merely means that the person who made it was dallying around at some time or other. It doesn't indicate guilt."

"Maybe so," conceded Heath doggedly. "But I'm here to tell you that if I get any good honest-to-God finger-prints outa this devastated area, it's not going so easy with the bird that made 'em."

Vance appeared to be shocked. "You positively terrify me, Sergeant. Henceforth I shall adopt mittens as a permanent addition to my attire. I'm always handling the furniture and the teacups and the various knickknacks in the houses where I call, don't y' know."

Markham interposed himself at this point, and suggested they make a tour of inspection while waiting for the Medical Examiner.

"They didn't add anything much to the usual methods," Heath pointed out. "Killed the girl, and then ripped things wide open."

The two rooms had apparently been thoroughly ransacked. Clothes and various articles were strewn about the floor. The doors of both clothes-closets (there was one in each room) were open, and to judge from the chaos in the bedroom closet, it had been hurriedly searched; although the closet off of the living-room, which was given over to the storage of infrequently used items, appeared to have been ignored. The drawers of the dressing-table and chest had been partly emptied on to the floor, and the bedclothes had been snatched away and the mattress turned back. Two chairs and a small occasional table were upset; several vases were broken, as if they had been searched and then thrown down in the wrath of disappointment; and the Marie Antoinette mirror had been broken. The escritoire was open, and its pigeonholes had been emptied in a jumbled pile upon the blotter. The doors of the Boule cabinet swung wide, and inside there was the same confusion of contents that marked the interior of the escritoire. The bronze-andporcelain lamp on the end of the librarytable was lying on its side, its satin shade
