“Tuesday, the 24th of July.”

“Exactly a week after the tragedy?”

“Yes.”

“You found these two objects, you say, in the chest of drawers. Was the drawer unlocked?”

“Yes.”

“Does it not strike you as unlikely that a man who had committed a crime should keep the evidence of it in an unlocked drawer for anyone to find?”

“He might have stowed them there in a hurry.”

“But you have just said it was a whole week since the crime. He would have had ample time to remove them and destroy them.”

“Perhaps.”
