Our new acquaintance very deliberately coiled up the tube of his hookah, and produced from behind a curtain a very long befrogged topcoat with Astrakhan collar and cuffs. This he buttoned tightly up, in spite of the extreme closeness of the night, and finished his attire by putting on a rabbit-skin cap with hanging lappets which covered the ears, so that no part of him was visible save his mobile and peaky face. “My health is somewhat fragile,” he remarked, as he led the way down the passage. “I am compelled to be a valetudinarian.”

Our cab was awaiting us outside, and our programme was evidently prearranged, for the driver started off at once at a rapid pace. Thaddeus Sholto talked incessantly, in a voice which rose high above the rattle of the wheels.

“Bartholomew is a clever fellow,” said he. “How do you think he found out where the treasure was? He had come to the conclusion that it was somewhere indoors: so he worked out all the cubic space of the house, and made measurements everywhere, so that not one inch should be unaccounted for. Among other things, he found that the height of the building was seventy-four feet, but on adding together the heights of all the separate rooms, and making every allowance for the space between, which he ascertained by borings, he could not bring the total to more than seventy feet. There were four feet unaccounted for. These could only be at the top of the building. He knocked a hole, therefore, in the lath-and-plaster ceiling of the highest room, and there, sure enough, he came upon another little garret above it, which had been sealed up and was known to no one. In the centre stood the treasure-chest, resting upon two rafters. He lowered it through the hole, and there it lies. He computes the value of the jewels at not less than half a million sterling.”
