“Look here, Gurney,” he said. “Come over and sit on this seat. I have something important to say to you.” He paused as if considering his words. “You thought a good deal of your employers, those two poor men who were lost on the moor?”

“An’ I had reason to. It wasn’t an accident ’appening in the execution of my dooty, as you might say, as made me lame and not fit to work. It was rheumatism, and they could ’ave let me go when I couldn’t work no more. But they found this job for me and they let me the ’ouse cheap.

“That’s it,” French went on, impressively. “Now, Gurney, I’m not accusing you of anything. But you know something. You needn’t attempt to deny it, because it has been plain to me from the first moment I spoke to you. Come now. Something out of the common took place that night. What was it?”
