"Indeed it is, sir. A good deal better looking than the other poor fellow, but directly I set eyes upon him I couldn't fail to see the likeness. And when he took off his gloves, and showed the big orange spots, I felt certain."

"I suppose you can lay hands upon him at any time?"

"Rather!" Prout grinned. "He's my prisoner. Arrested him tonight in connection with some long firm frauds. I arrested him in his own lodgings so that I should have a chance to search the room, and what did I come across but a few letters written by the murdered man to this brother of his."

"Surely, a curious coincidence!" Lawrence cried.

"Not at all, sir. There's a marvellous freemasonry amongst criminals. I've started a hunt for a watch and chain, and found a bank robbery. Once in looking for a missing man I dropped upon a sensational bankruptcy. One never knows. But touching these letters. They are undoubtedly the same handwriting as the letter we found on the Corner House victim. I've put them together, and I am certain."

"Do they contain anything likely to help us, Prout?"

"Well, that I can't say for the present, sir," Prout replied. "I have only looked at one. Seeing that you are so interested, I came here at once. But one thing I have discovered--if I was a creditor of a certain Countess who shall be nameless, I should go and sit on the doorstep until I had got the money."

Lawrence winked never so slightly. He had his own ideas on that head. He read the one letter that Prout handed to him and smiled. Beyond doubt the letter had been written by the queer misshapen outcast who had been found dead in the Corner House. As Lawrence returned the letter he looked at his watch.

"It wants some time of two o'clock yet," he said. "My friend, Dr. Bruce, does not go to bed early, so I shall go round and look him up. We'll go into the other letters carefully when we have time, Prout, but for the present I should like to borrow this one if you have no objection. What do you say?"

Prout had no objection to make. He had made a great discovery, but he felt pretty sure that he would need Lawrence's ingenious mind and fine imagination before he had succeeded in solving the problem.
