"Doesn't it strike you that there are at least two very strong points against that theory?" he asked, making two gigantic knots in his piece of string.

"Two?"

"Yes. In the first place, if the blackmailer was the 'Comte de la Tremouille' returned to life, why should he have been content to take £10,000 from a lady who was his lawful wife, and who could keep him in luxury for the rest of his natural life upon her large fortune, which was close upon a quarter of a million? The real Comte de la Tremouille, remember, had never found it difficult to get money out of his wife during their brief married life, whatever Mr. Morton's subsequent experience in the same direction might have been. And, secondly, why should he have typewritten his letters to his wife?"

"Because—"

"That was a point which, to my mind, the police never made the most of. Now, my experience in criminal cases has invariably been that when a typewritten letter figures in one, that letter is a forgery. It is not very difficult to imitate a signature, but it is a jolly sight more difficult to imitate a handwriting throughout an entire letter."

"Then, do you think—"

"I think, if you will allow me," he interrupted excitedly, "that we will go through the points—the sensible, tangible points of the case. Firstly: Mr. Morton disappears with £10,000 in his pocket for four entire days; at the end of that time he is discovered loosely tied to an arm-chair, and a wool shawl round his mouth. Secondly: A man named Skinner is accused of the outrage. Mr. Morton, although he himself is able, mind you, to furnish the best defence possible for Skinner, by denying his identity with the man who assaulted him, refuses to prosecute. Why?"

"He did not wish to drag his wife's name into the case."

"He must have known that the Crown would take up the case. Then, again, how is it no one saw him in the company of the swarthy foreigner he described?"

"Two witnesses did see Mr. Morton in company with Skinner," argued Polly.
