“And then?”
“I returned here between eleven and twelve o’clock.”
“To make a call?”
“No, I came upon an errand.”
“What was the errand?”
“As it has no bearing upon the case, I think it is my privilege to decline to answer.”
“You entered the house with a latch-key.”
“I did.”
“Is that latch-key your own property?”
“For the time, yes. Mrs. Markham gave it to me a few days ago, for my convenience, because I have occasion to come to the house so frequently.”
