"No," replied the old man; "my eyesight's that bad as I can hardly tell A from B. It was the picture of a bearded man."

"A pointed beard?"

"I can't say. He had a beard, that's all I know. Mrs. Brand said that his business took him away a good deal. But she didn't say he was a commercial gent."

"Did Mrs. Brand, go out much?"

"Not at all. I told you so before. She kept very much to herself, in a haughty kind of way. Thought herself a fine lady, I suppose, and there's no denying she was a lady. She has been my tenant for over five years, and always paid regular, but she knew no one, and when any one called she never would let them in. I only got to know of this room because I came for my rent."

"Did she pay her bills regularly?"

"Yes. I asked that, being fearful for my rent. She always paid up like a lady. Not that she took much in. Generally she lived by herself, so didn't eat much, keeping no servant either."

"Did she ever go out to concerts or theatres or anywhere?"

"When her husband came home she used to enjoy herself. I believe she went to the opera, or to concerts, being fond of music."

"Ah!" Derrick recalled the song. "Did she sing?"
