forward," he called.

The men stood mute, eyeing one another expectantly, each hoping someone else might have valuable information to offer. The hush finally was broken by a shuffling of feet as two strangers thrust their way through the crowd and ranged themselves on either side of the coroner.

One of the newcomers, the less heavily built of the two, compelled immediate attention by reason of his personality. He carried himself with an air of certainty, as if accustomed to meeting grave problems—and solving them. As he stood at the right of the coroner, his keen gray eyes, set deep beneath the arched outline of his eyebrows, swept the faces of the sorrowing employés, as if trying to read their inmost thoughts. Despite the severe cast of his features, there was something engaging about the man, some magic of personality, that drew one irresistibly toward him.

"Just in time to hear the most important witness," the coroner said to him, at the same time beckoning the office boy to come forward.

The two visitors and the coroner seated themselves at one of the flat-top desks, while the boy, pale, trembling, as if conscious of some guilty act, faced them with fear written in his youthful countenance. The coroner solemnly administered the customary oath.

"You know what will happen to you if you tell a lie?" he asked.

"Yes, sir, I'll be sent to prison," the boy answered timorously.

"Now what is your name?"

"Samuel Johnson."

The witness further confided that he had been employed in the establishment three years, that he had seen Mr. Whitmore enter the office and that thereafter he had occupied a seat within a foot of the door until one of the clerks called his attention to the peculiar attitude in which his employer had fallen in the chair.

"What did Mr. Whitmore say to you when he arrived this morning?" inquired the coroner.

"He'd been away for six weeks, and he put his hand on my head like he was glad to see me and said that no one was to be admitted to the office and I wasn't to bring in any visitor's card." The boy sobbed convulsively as he recalled the last words of his employer.

"Were any visitors here this morning?"

"No, sir."

"Did any of the clerks enter the office?"

"No, sir."

"Did you hear a shot fired, or any other peculiar sound?"

"I did not."

"Are you positive?"

"I hope I may die on the spot if it ain't so," the witness said fervently.

The coroner's eyes alternated between his two visitors. The smaller of the two devoted himself to a long scrutiny of the boy's countenance.

"Mr. Whitmore was absent for six weeks?" he suddenly asked.

"Yes, sir."

"Do you know where he was?"

"Mr. Beard told me to tell all visitors that Mr. Whitmore was away on a business trip."

"Who is Mr. Beard?"

"Mr. Whitmore's confidential secretary. He took charge of the business while Mr. Whitmore was away."

"Isn't it somewhat unusual that nobody called to see Mr. Whitmore on his return this morning?"

"I guess they didn't know he was back," the boy replied.

"Did Mr. Whitmore have any trouble with anyone before he left?"

"Not that I know of. But after he was gone a man came around here every day for four weeks looking for him. The man looked like a Broadway dude—like he drank a whole lot and didn't sleep much. I once heard him tell Mr. Beard that Mr. Whitmore had run away from him."

The coroner and the visitors exchanged meaning glances.

"Where is Mr. Beard?" inquired the coroner.

"He didn't come down to-day."

Again the coroner looked gravely at the others, but their faces failed to indicate what import they attached to the boy's statements.

"Lieutenant, is there any other question you desire to ask?"

"No, coroner, I think we'd better adjourn to the private office," said the man addressed.

Entering the merchant's office, the coroner closed the door behind them.

"Lieutenant Britz," he remarked cordially, "I'm glad they sent you up. This looks like a mystery worthy of your talents."

Lieutenant Britz disregarded the implied compliment. He had taken up a position of survey in the center of the room, from which his eyes traveled slowly about the place, studying every inch of the carpet, lingering on the black leather surface of the chairs, covering the wide area of the walls.

"Have you searched the body?" he asked.

"Yes," replied the coroner. "Only a key ring with four keys attached was found in the pockets."

"How about the papers in the desk?"

"Nothing but business papers."

At this juncture a clerk poked his head timidly into the room and said:

"Officers, it's three o'clock now and we haven't been out to lunch. May we go?"

"I'll let you know in a minute or two," answered the coroner. When the clerk had withdrawn his head, the official stepped over to Britz.

"Those clerks are in a conspiracy of silence," he declared. "This man could not have committed suicide. The pistol found on the desk was fully loaded. The clothing is devoid of powder stains. Moreover, a most careful search has failed to reveal any other weapon. Now, someone entered this room and fired the shot. Yet all those clerks maintain that no one has been in here and that they heard no shot, although the door stood open all the while the merchant was in the office. Somebody has secreted the pistol with which the shooting was done and it might be well to search all the clerks."

"That would be a useless procedure," replied Britz. "There is no conspiracy of silence. If those men outside could shed any light on the crime, they would do so eagerly. The murderer could not have enjoined silence on thirty or thirty-five men. No, they have told all they know. You may permit them to enjoy their lunch."

Although the coroner was the ranking official, his respect for Britz's judgment was such that he invariably followed the latter's suggestions. So he informed the clerks they could leave the building at will.

While the coroner was in the big room addressing the employés, Britz suddenly walked to the chair in which the murdered man still sat huddled. Bending down, he picked up something long and shiny, which the others had overlooked. It was a long darning needle, and the detective, after examining it an instant under the electric light, slipped it into a leather card case. He did not mention what he had found to the coroner, when the latter returned.

"Greig," said Britz to his bulky companion, "go out and fetch a step-ladder. Let us examine the walls and ceiling."

Greig hastened out of the office, returning in a few minutes with the ladder. The two detectives devoted half an hour to sounding the walls and ceiling, while the coroner wrote out the necessary permit for the removal of the body.

"Everything is absolutely solid," declared Britz, when he had finished his examination. "There are no panels in the wall through which the assassin might have entered."

"That's what I thought," beamed the coroner. "The murderer entered and left through the door. And some of those clerks, if not all of them, must have seen him—or her. I tell you they're in a conspiracy to shield the murderer."

Britz extended a hand toward the glass partition.

"Look down this room," he said. "The murderer, presuming it was a man, must have passed down this long aisle into the office. Then, it was necessary to repeat the journey in order to escape. Had there been a conspiracy, then those thirty clerks must have remained quietly at their desks while the assassin walked out of the room. Do you believe these men would have permitted him to escape?"

"Suppose he carried the pistol in his hand, don't you believe he could have intimidated them?" ventured Greig.

"Sure!" joined the coroner. "And the men may now be ashamed of their cowardice."

"That wouldn't have prevented them giving the alarm after the murderer left," declared Britz. "No, coroner, no
