Some ten minutes passed of question, answer, and laborious caligraphy, then voices and steps were heard on the stairs, and four men entered the room.

“What’s all this, Alcorn?” cried the first, a stout, clean-shaven man with the obvious stamp of authority, in the same phrase that his subordinate had used to the clerk, Orchard. He had stepped just inside the door, and stood looking sharply round the room, his glance passing from the constable to the body, to the open safe, with inimical interest to the young clerk, and back again to Alcorn.

The constable stiffened to attention, and replied in a stolid, unemotional tone, as if reciting formal evidence in court.

“I was on my beat, sir, and at about ten-fifteen was just turning the corner from Charles Street into Hatton Garden, when I observed this young man,” he indicated Orchard with a gesture, “run out of the door of this house. He called me that there was something wrong up here, and I came up to see, and found that body lying as you see it. Nothing has been touched, but I have got some information here for you.” He held up the notebook.

The newcomer nodded and turned to one of his companions, a tall man with the unmistakable stamp of the medical practitioner.

“If you can satisfy yourself the man’s dead, Doctor, I don’t think we shall disturb the body in the meantime. It’ll probably be a case for the Yard, and if so we’ll leave everything for whoever they send.”

The doctor crossed the room and knelt by the remains.

“He’s dead all right,” he announced, “and not so long ago either. If I could turn the body over I could tell you more about that. But I’ll leave it if you like.”

“Yes, leave it for the moment, if you please. Now, Alcorn, what else do you know?”

A few seconds sufficed to put the constable’s information at his superior’s disposal. The latter turned to the doctor.
