"No, but I saw you coming into Leicester Square."
"How did you find me out?" I asked, rather nettled. "I thought my disguise a good one."
"So it was. There isn't one in a thousand who would have recognized you. I happen to be that one. You see, Godfrey, when you are thinking of something very particular, you have a nasty habit of stroking your chin with the middle finger of your right hand."
"Good," said I, "you will never catch me doing that again when I'm somebody else. Well?"
"Seeing that, I took special notice of you, and followed you home to make sure. When you stopped at 719 Buckingham Palace Road, and let yourself in, I was satisfied it was you."
"There's nothing very smart in that."
"I don't say there is. I kept myself out of sight, for a reason you'll appreciate."
"Out with it."
"I wasn't the only one who was following you."
"You don't mean to say I was being shadowed?" I cried, excitedly.
