The lad continued his work without regarding us. I saw Holmes’s eye darting to right and left among the litter of iron and wood which was scattered about the floor. Suddenly, however, we heard a step behind us, and there was the landlord, his heavy eyebrows drawn over his savage eyes, his swarthy features convulsed with passion. He held a short, metal-headed stick in his hand, and he advanced in so menacing a fashion that I was right glad to feel the revolver in my pocket.

“You infernal spies!” the man cried. “What are you doing there?”

“Why, Mr. Reuben Hayes,” said Holmes, coolly, “one might think that you were afraid of our finding something out.”

The man mastered himself with a violent effort, and his grim mouth loosened into a false laugh, which was more menacing than his frown.
