I placed my revolver, cocked, upon the top of the wooden case behind which I crouched. Holmes shot the slide across the front of his lantern and left us in pitch darkness—such an absolute darkness as I have never before experienced. The smell of hot metal remained to assure us that the light was still there, ready to flash out at a moment’s notice. To me, with my nerves worked up to a pitch of expectancy, there was something depressing and subduing in the sudden gloom, and in the cold dank air of the vault.
“They have but one retreat,” whispered Holmes. “That is back through the house into Saxe-Coburg Square. I hope that you have done what I asked you, Jones?”
“I have an inspector and two officers waiting at the front door.”
“Then we have stopped all the holes. And now we must be silent and wait.”
What a time it seemed! From comparing notes afterwards it was but an hour and a quarter, yet it appeared to me that the night must have almost gone, and the dawn be breaking above us.
