"I arrived in London yesterday afternoon."
"But you did not come down to Marley until this morning?"
"No, Superintendent, I did not."
"Where did you go, Mr. North?"
"To my flat, Superintendent."
"Where is that, if you please?"
"In Portland Place."
"Was that usual?"
"Quite."
"You will have to forgive my bluntness, Mr. North, but I must ask you to explain yourself a little more fully. Do you and Mrs. North inhabit separate establishments?"
