"And only until next Tuesday, when he will take a house in the neighborhood of Scotland Yard," put in Holmes, quickly, observing a sneer on Hawkshaw's lips, and hastening to overwhelm him by further evidence of his ingenuity. "When he gets his bill he will open his piratical eyes so wide that he will be seized with jealousy to think of how much more refined his profession has become since he left it, and out of mere pique he will leave the hotel, and, to show himself still cleverer than his modern prototypes, he will leave his account unpaid, with the result that the affair will be put in the hands of the police, under which circumstances a house in the immediate vicinity of the famous police headquarters will be the safest hiding-place he can find, as was instanced by the remarkable case of the famous Penstock bond robbery. A certain church-warden named Hinkley, having been appointed cashier thereof, robbed the Penstock Imperial Bank of L1,000,000 in bonds, and, fleeing to London, actually joined the detective force at Scotland Yard, and was detailed to find himself, which of course he never did, nor would he ever have been found had he not crossed my path." Hawkshaw gazed mournfully off into space, and Le Coq muttered profane words under his breath. "We're not in the same class with this fellow, Hawkshaw," said Le Coq. "You could tap your forehead knowingly eight hours a day through all eternity with a sledge-hammer without loosening an idea like that." "Nevertheless I'll confound him yet," growled the jealous detective. "I shall myself go to London, and, disguised as Captain Kidd, will lead this visionary on until he comes there to arrest me, and when these club members discover that it is Hawkshaw and not Kidd he has run to earth, we'll have a great laugh on Sherlock Holmes." "I am anxious to hear how you solved the bond-robbery mystery," said Socrates, wrapping his toga closely about him and settling back against one of the spiles of the wharf. "So are we all," said Sir Walter. "But meantime the House-boat is getting farther away." "Not unless she's sailing backwards," sneered Noah, who was still nursing his resentment against Sir Christopher Wren for his reflections upon the speed of the Ark. "What's the hurry?" asked Socrates. "I believe in making haste slowly; and on the admission of our two eminent naval architects, Sir Christopher and Noah, neither of their vessels can travel more than a mile a week, and if we charter the _Flying Dutchman_ to go in pursuit of her we can catch her before she gets out of the Styx into the Atlantic."
