Only once during all those months did I ever see him without that sad but impassive mask which he usually presented towards his fellow-man. For an instant I caught a glimpse of those volcanic fires which he had damped down so long. The occasion was an unworthy one, for the object of his wrath was none other than the aged charwoman whom I have already mentioned as being the one person who was allowed within his mysterious chamber. I was passing the corridor which led to the turret--for my own room lay in that direction--when I heard a sudden, startled scream, and merged in it the husky, growling note of a man who is inarticulate with passion. It was the snarl of a furious wild beast. Then I heard his voice thrilling with anger. "You would dare!" he cried. "You would dare to disobey my directions!" An instant later the charwoman passed me, flying down the passage, white faced and tremulous, while the terrible voice thundered behind her. "Go to Mrs. Stevens for your money! Never set foot in Thorpe Place again!" Consumed with curiosity, I could not help following the woman, and found her round the corner leaning against the wall and palpitating like a frightened rabbit.

"What is the matter, Mrs. Brown?" I asked.
"It's master!" she gasped. "Oh 'ow 'e frightened me! If you 'ad seen 'is eyes, Mr. Colmore, sir. I thought 'e would 'ave been the death of me."
"Done, sir! Nothing. At least nothing to make so much of. Just laid my 'and on that black box of 'is--'adn't even opened it, when in 'e came and you 'eard the way 'e went on. I've lost my place, and glad I am of it, for I would never trust myself within reach of 'im again."
So it was the japanned box which was the cause of this outburst--the box from which he would never permit himself to be separated. What was the connection, or was there any connection between this and the secret visits of the lady whose voice I had overheard? Sir John Bollamore's wrath was enduring as well as fiery, for from that day Mrs. Brown, the charwoman, vanished from our ken, and Thorpe Place knew her no more.
And now I wish to tell you the singular chance which solved all these strange questions and put my employer's secret in my possession. The story may leave you with some lingering doubt as to whether my curiosity did not get the better of my honour, and whether I did not condescend to play the spy. If you choose to think so I cannot help it, but can only assure you that, improbable as it may appear, the matter came about exactly as I describe it.
