"He was a stranger, then?"
"Yes, sir; I never met him till this morning."
"Then I think I can tell you where your money has gone."
"Where, sir?" demanded Walter, beginning to understand him.
"I think your late companion was a pickpocket, and relieved you of it, while he pretended to be reading. I didn't like his appearance much."
"I don't see how he could have done it without my feeling his hand in my pocket."
"They understand their business, and can easily relieve one of his purse undetected. I once had my watch stolen without being conscious of it. Your porte-monnaie was in the pocket towards the man, and you were looking from the window. It was a very simple thing to relieve you of it."
