Part 6 (2/2)

”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 employes, Britz suddenly walked to the chair in which the murdered man still sat huddled. Bending down, he picked up something long and s.h.i.+ny, 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 a.s.sa.s.sin 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 s.h.i.+eld the murderer.”

Britz extended a hand toward the gla.s.s part.i.tion.

”Look down this room,” he said. ”The murderer, presuming it was a man, must have pa.s.sed 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 a.s.sa.s.sin 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 one saw the slayer enter or leave. In fact, he did not enter through the door.”

”Then how did he get in?” demanded the coroner. ”Through the wall? Or did he fire through the ceiling or floor?”

”As I said before, there is no secret panel in this room,” was Britz's rejoinder.

”Then you believe Mr. Whitmore committed suicide?” suddenly fired the coroner.

”No.”

”He might have committed suicide, and the clerks, out of regard for their employer, subst.i.tuted pistols in order to make it appear like murder,” joined Greig.

”Perhaps,” replied Britz. ”Relatives and friends frequently endeavor to give a case of suicide the aspect of murder.”

”But you don't really believe it of this case?” asked the coroner.

”I do not,” confessed Britz.

”Then your theory must be that some invisible person fired a silent shot”--the coroner paused a moment, then as if struck by a sudden thought--”of course, a Maxim m.u.f.fler might have deadened the sound of the pistol.”

”The office boy would have heard the click of the hammer,” interposed Britz.

The coroner repressed with difficulty the smile that struggled to his lips.
