# The Benson Murder Case/Chapter 9

(Saturday, June 15; 5 p.m.)
When we arrived at Benson's house a patrolman leaning somnolently against the iron paling of the areaway came suddenly to attention and saluted. He eyed Vance and me hopefully, regarding us no doubt as suspects being taken to the scene of the crime for questioning by the District Attorney. We were admitted by one of the men from the Homicide Bureau who had been in the house on the morning of the investigation.
Markham greeted him with a nod.
"Everything going all right?"
"Sure," the man replied good-naturedly. "The old lady's as meek as a cat—and a swell cook."
"We want to be alone for a while, Sniffin," said Markham, as we passed into the living-room.
"The gastronome's name is Snitkin—not Sniffin," Vance corrected him, when the door had closed on us.
"Wonderful memory," muttered Markham churlishly.
"A failing of mine," said Vance. "I suppose you are one of those rare persons who never forget a face but just can't recall names, what?"
​But Markham was in no mood to be twitted.
"Now that you've dragged me here, what are you going to do?" He waved his hand depreciatingly, and sank into a chair with an air of contemptuous abdication.
The living-room looked much the same as when we saw it last, except that it had been put neatly in order. The shades were up, and the late afternoon light was flooding in profusely. The ornateness of the room's furnishings seemed intensified by the glare.
Vance glanced about him and gave a shudder.
"I'm half inclined to turn back," he drawled. "It's a clear case of justifiable homicide by an outraged interior decorator."
"My dear æsthete," Markham urged impatiently, "be good enough to bury your artistic prejudices, and to proceed with your problem. . . . Of course," he added, with a malicious smile, "if you fear the result, you may still withdraw, and thereby preserve your charming theories in their present virgin state."
"And permit you to send an innocent maiden to the chair!" exclaimed Vance, in mock indignation. "Fie, fie! La politesse alone forbids my withdrawal. May I never have to lament, with Prince Henry, that 'to my shame I have a truant been to chivalry'."
Markham set his jaw, and gave Vance a ferocious look.
"I'm beginning to think that, after all, there is something in your theory that every man has some motive for murdering another."
"Well," replied Vance cheerfully, "now that you ​have begun to come round to my way of thinking, do you mind if I send Mr. Snitkin on an errand?"
Markham sighed audibly and shrugged his shoulders.
"I'll smoke during the opéra bouffe, if it won't interfere with your performance."
Vance went to the door and called Snitkin.
"I say, would you mind going to Mrs. Platz and borrowing a long tape-measure and a ball of string. . . . The District Attorney wants them," he added, giving Markham a sycophantic bow.
"I can't hope that you're going to hang yourself, can I?" asked Markham.
Vance gazed at him reprovingly.
"Permit me," he said sweetly, "to commend Othello to your attention:
Or—to descend from a poet to a platitudinarian—let me present for your consid'ration a pentameter from Longfellow: 'All things come round to him who will but wait.' Untrue, of course, but consolin'. Milton said it much better in his 'They also serve—'. But Cervantes said it best: 'Patience and shuffle the cards.' Sound advice, Markham—and advice expressed rakishly, as all good advice should be. . . . To be sure, patience is a sort of last resort—a practice to adopt when there's nothing else to do. Still, like virtue, it occasionally rewards the practitioner; although I'll admit that, as a rule, it is—again like virtue—bootless. That is to say, it is its ​own reward. It has, however, been swathed in many verbal robes. It is 'sorrow's slave,' and the 'sov'reign o'er transmuted ills,' as well as 'all the passion of great hearts.' Rousseau wrote, La patience est amère mais son fruit est doux. But perhaps your legal taste runs to Latin. Superanda omnis fortuna ferendo est, quoth Vergil. And Horace also spoke on the subject. Durum! said he, sed levius fit patientia——"
"Why the hell doesn't Snitkin come?" growled Markham.
Almost as he spoke the door opened, and the detective handed Vance the tape-measure and string.
"And now, Markham, for your reward!"
Bending over the rug Vance moved the large wicker chair into the exact position it had occupied when Benson had been shot. The position was easily determined, for the impressions of the chair's castors on the deep nap of the rug were plainly visible. He then ran the string through the bullet-hole in the back of the chair, and directed me to hold one end of it against the place where the bullet had struck the wainscot. Next he took up the tape-measure and, extending the string through the hole, measured a distance of five feet and six inches along it, starting at the point which corresponded to the location of Benson's forehead as he sat in the chair. Tying a knot in the string to indicate the measurement, he drew the string taut, so that it extended in a straight line from the mark on the wainscot, through the hole in the back of the chair, to a point five feet and six inches in front of where Benson's head had rested.
"This knot in the string," he explained, "now ​represents the exact location of the muzzle of the gun that ended Benson's career. You see the reasoning—eh, what? Having two points in the bullet's course—namely, the hole in the chair and the mark on the wainscot—, and also knowing the approximate vertical line of explosion, which was between five and six feet from the gentleman's skull, it was merely necess'ry to extend the straight line of the bullet's course to the vertical line of explosion in order to ascertain the exact point at which the shot was fired."
"Theoretically very pretty," commented Markham; "though why you should go to so much trouble to ascertain this point in space I can't imagine. . . . Not that it matters, for you have overlooked the possibility of the bullet's deflection."
"Forgive me for contradicting you," smiled Vance; "but yesterday morning I questioned Captain Hagedorn at some length, and learned that there had been no deflection of the bullet. Hagedorn had inspected the wound before we arrived; and he was really pos'tive on that point. In the first place, the bullet struck the frontal bone at such an angle as to make deflection practically impossible even had the pistol been of smaller calibre. And in the second place, the pistol with which Benson was shot was of so large a bore—a point-forty-five—and the muzzle velocity was so great, that the bullet would have taken a straight course even had it been held at a greater distance from the gentleman's brow."
"And how," asked Markham, "did Hagedorn know what the muzzle velocity was?"
"I was inquis'tive on that point myself," answered Vance; "and he explained that the size and character ​of the bullet and the expelled shell told him the whole tale. That's how he knew the gun was an army Colt automatic—I believe he called it a U. S. Government Colt—and not the ordinary Colt automatic. The weight of the bullets of these two pistols is slightly different: the ordinary Colt bullet weighs 200 grains, whereas the army Colt bullet weighs 230 grains. Hagedorn, having a hypersensitive tactile sense, was able, I presume, to distinguish the diff'rence at once, though I didn't go into his physiological gifts with him,—my reticent nature, you understand. . . . However, he could tell it was a forty-five army Colt automatic bullet; and knowing this, he knew that the muzzle velocity was 809 feet, and that the striking energy was 329—which gives a six-inch penetration in white pine at a distance of twenty-five yards. . . . An amazin' creature, this Hagedorn. Imagine having one's head full of such entrancing information! The old mysteries of why a man should take up the bass-fiddle as a life work and where all the pins go, are babes' conundrums compared with the one of why a human being should devote his years to the idiosyncrasies of bullets."
"The subject is not exactly an enthralling one," said Markham wearily; "so, for the sake of argument, let us admit that you have now found the precise point of the gun's explosion. Where do we go from there?"
"While I hold the string on a straight line," directed Vance, "be good enough to measure the exact distance from the floor to the knot. Then my secret will be known."
​"This game doesn't enthrall me, either," Markham protested. "I'd much prefer 'London Bridge'."
Nevertheless he made the measurement.
"Four feet, eight and a half inches," he announced indifferently.
Vance laid a cigarette on the rug at a point directly beneath the knot.
"We now know the exact height at which the pistol was held when it was fired. . . . You grasp the process by which this conclusion was reached, I'm sure."
"It seems rather obvious," answered Markham.
Vance again went to the door and called Snitkin.
"The District Attorney desires the loan of your gun for a moment," he said. "He wishes to make a test."
Snitkin stepped up to Markham and held out his pistol wonderingly.
"The safety's on, sir: shall I shift it?"
Markham was about to refuse the weapon when Vance interposed.
"That's quite all right. Mr. Markham doesn't intend to fire it—I hope."
When the man had gone Vance seated himself in the wicker chair, and placed his head in juxtaposition with the bullet-hole.
"Now, Markham," he requested, "will you please stand on the spot where the murderer stood, holding the gun directly above that cigarette on the floor, and aim delib'rately at my left temple. . . . Take care," he cautioned, with an engaging smile, "not to pull the trigger, or you will never learn who killed Benson."
​Reluctantly Markham complied. As he stood taking aim, Vance asked me to measure the height of the gun's muzzle from the floor.
The distance was four feet and nine inches.
"Quite so," he said, rising. "Y' see, Markham, you are five feet, eleven inches tall; therefore the person who shot Benson was very nearly your own height—certainly not under five feet, ten. . . . That, too, is rather obvious, what?"
His demonstration had been simple and clear. Markham was frankly impressed; his manner had become serious. He regarded Vance for a moment with a meditative frown; then he said:
"That's all very well; but the person who fired the shot might have held the pistol relatively higher than I did."
"Not tenable," returned Vance. "I've done too much shooting myself not to know that when an expert takes delib'rate aim with a pistol at a small target, he does it with a stiff arm and with a slightly raised shoulder, so as to bring the sight on a straight line between his eye and the object at which he aims. The height at which one holds a revolver, under such conditions, pretty accurately determines his own height."
"Your argument is based on the assumption that the person who killed Benson was an expert taking deliberate aim at a small target?"
"Not an assumption, but a fact," declared Vance. "Consider: had the person not been an expert shot, he would not—at a distance of five or six feet—have selected the forehead, but a larger target—namely, the breast. And having selected the forehead, he ​most certainly took delib'rate aim, what? Furthermore, had he not been an expert shot, and had he pointed the gun at the breast without taking delib'rate aim, he would, in all prob'bility, have fired more than one shot."
Markham pondered.
"I'll grant that, on the face of it, your theory sounds plausible," he conceded at length. "On the other hand, the guilty man could have been almost any height over five feet, ten; for certainly a man may crouch as much as he likes and still take deliberate aim."
"True," agreed Vance. "But don't overlook the fact that the murderer's position, in this instance, was a perfectly natural one. Otherwise, Benson's attention would have been attracted, and he would not have been taken unawares. That he was shot unawares was indicated by his attitude. Of course, the assassin might have stooped a little without causing Benson to look up. . . . Let us say, therefore, that the guilty person's height is somewhere between five feet, ten, and six feet, two. Does that appeal to you?"
Markham was silent.
"The delightful Miss St. Clair, y' know," remarked Vance, with a japish smile, "can't possibly be over five feet, five or six."
Markham grunted, and continued to smoke abstractedly.
"This Captain Leacock, I take it," said Vance, "is over six feet—eh, what?"
Markham's eyes narrowed.
"What makes you think so?"
​"You just told me, don't y' know."
"I told you!"
"Not in so many words," Vance pointed out. "But after I had shown you the approximate height of the murderer, and it didn't correspond at all to that of the young lady you suspected, I knew your active mind was busy looking around for another possibility. And, as the lady's inamorato was the only other possibility on your horizon, I concluded that you were permitting your thoughts to play about the Captain. Had he, therefore, been the stipulated height, you would have said nothing; but when you argued that the murderer might have stooped to fire the shot, I decided that the Captain was inord'nately tall. . . . Thus, in the pregnant silence that emanated from you, old dear, your spirit held sweet communion with mine, and told me that the gentleman was a six-footer no less."
"I see that you include mind-reading among your gifts," said Markham. "I now await an exhibition of slate-writing."
His tone was irritable, but his irritation was that of a man reluctant to admit the alteration of his beliefs. He felt himself yielding to Vance's guiding rein, but he still held stubbornly to the course of his own previous convictions.
"Surely you don't question my demonstration of the guilty person's height?" asked Vance mellifluously.
"Not altogether," Markham replied. "It seems colorable enough. . . . But why, I wonder, didn't Hagedorn work the thing out, if it was so simple?"
"Anaxagoras said that those who have occasion ​for a lamp, supply it with oil. A profound remark, Markham—one of those seemingly simple quips that contain a great truth. A lamp without oil, y' know, is useless. The police always have plenty of lamps—every variety, in fact—but no oil, as it were. That's why they never find anyone unless it's broad daylight."
Markham's mind was now busy in another direction, and he rose and began to pace the floor.
"Until now I hadn't thought of Captain Leacock as the actual agent of the crime."
"Why hadn't you thought of him? Was it because one of your sleuths told you he was at home like a good boy that night?"
"I suppose so." Markham continued pacing thoughtfully. Then suddenly he swung about. "That wasn't it, either. It was the amount of damning circumstantial evidence against the St. Clair woman. . . . And, Vance, despite your demonstration here to-day, you haven't explained away any of the evidence against her.—Where was she between twelve and one? Why did she go with Benson to dinner? How did her hand-bag get here? And what about those burned cigarettes of hers in the grate?—they're the obstacle, those cigarette butts; and I can't admit that your demonstration wholly convinces me—despite the fact that it is convincing—as long as I've got the evidence of those cigarettes to contend with, for that evidence is also convincing."
"My word!" sighed Vance. "You're in a pos'tively ghastly predic'ment. However, maybe I can cast illumination on those disquietin' cigarette butts."
​Once more he went to the door, and summoning Snitkin, returned the pistol.
"The District Attorney thanks you," he said. "And will you be good enough to fetch Mrs. Platz. We wish to chat with her."
Turning back to the room, he smiled amiably at Markham.
"I desire to do all the conversing with the lady this time, if you don't mind. There are potentialities in Mrs. Platz which you entirely overlooked when you questioned her yesterday."
Markham was interested, though sceptical.
"You have the floor," he said.
