"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."
At the mention of this gigantic sum we all stared at one another open-eyed. Miss Morstan, could we secure her rights, would change from a needy governess to the richest heiress in England. Surely it was the place of a loyal friend to rejoice at such news; yet I am ashamed to say that selfishness took me by the soul, and that my heart turned as heavy as lead within me. I stammered out some few halting words of congratulation, and then sat downcast, with my head drooped, deaf to the babble of our new acquaintance. He was clearly a confirmed hypochondriac, and I was dreamily conscious that he was pouring forth interminable trains of symptoms, and imploring information as to the composition and action of innumerable quack nostrums, some of which he bore about in a leather case in his pocket. I trust that he may not remember any of the answers which I gave him that night. Holmes declares that he overheard me caution him against the great danger of taking more than two drops of castor oil, while I recommended strychnine in larger doses as a sedative. However that may be, I was certainly relieved when our cab pulled up with a jerk and the coachman sprang down to open the door.
"This, Miss Morstan, is Pondicherry Lodge," said Mr. Thaddeus Sholto, as he handed her out.
The Tragedy of Pondicherry Lodge
It was nearly eleven o'clock when we reached this final stage of our night's adventures. We had left the damp fog of the great city behind us, and the night was fairly fine. A warm wind blew from the westward, and heavy clouds moved slowly across the sky, with half a moon peeping occasionally through the rifts. It was clear enough to see for some distance, but Thaddeus Sholto took down one of the side-lamps from the carriage to give us a better light upon our way.
Pondicherry Lodge stood in its own grounds, and was girt round with a very high stone wall topped with broken glass. A single narrow, iron-clamped door formed the only means of entrance. On this our guide knocked with a peculiar postman-like rat-tat.
"Who is there?" cried a gruff voice from within.
"It is I, McMurdo. You surely know my knock by this time."
There was a grumbling sound, and a clanking and jarring of keys. The door swung heavily back, and a short, deep-chested man stood in the opening, with the yellow light of the lantern shining upon his protruded face and twinkling, distrustful eyes.
