"Oh, you did?" replied Inspector Chippenfield. "And why was that?"
"Because of my past."
"Where were you on the date of the murder?"
"In the morning I came over here to look round as usual, and I found everything all right."
"You did that every day while Sir Horace was away?"
"Not every day, sir. Three times a week: Mondays, Wednesdays, and
Fridays."
"Did you enter the house or just look round?"
"I always came inside."
"What for?"
"To make quite sure that everything was all right."
