ound 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 large 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.

Chapter V

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 Tha
