“Quick, Watson, quick! Get it back again!” The wooden lid was replaced, and the drugget had only just been drawn straight when Lestrade's voice was heard in the passage. He found Holmes leaning languidly against the mantelpiece, resigned and patient, endeavouring to conceal his irrepressible yawns.

“Sorry to keep you waiting, Mr. Holmes. I can see that you are bored to death with the whole affair. Well, he has confessed, all right. Come in here, MacPherson. Let these gentlemen hear of your most inexcusable conduct.”

The big constable, very hot and penitent, sidled into the room.

“I meant no harm, sir, I'm sure. The young woman came to the door last evening—mistook the house, she did. And then we got talking. It's lonesome, when you're on duty here all day.”

“Well, what happened then?”

“She wanted to see where the crime was done—had read about it in the papers, she said. She was a very respectable, well-spoken young woman, sir, and I saw no harm in letting her have a peep. When she saw that mark on the carpet, down she dropped on the floor, and lay as if she were dead. I ran to the back and got some water, but I could not bring her to. Then I went round the corner to the Ivy Plant for some brandy, and by the time I had brought it back the young woman had recovered and was off—ashamed of herself, I dare say, and dared not face me.”

“How about moving that drugget?”

“Well, sir, it was a bit rumpled, certainly, when I came back. You see, she fell on it, and it lies on a polished floor with nothing to keep it in place. I straightened it out afterwards.”
