Jock hooted with laughter. He sounded so cheerful, that I perforce laughed too, and then I gazed at him sombrely.
"Jock," I said, "you are a fraud and a disappointment."
He laughed again, and then all at once a much more sensible idea struck me. He was not a very promising ally, but he might prove better than none at all.
"Jock," said I, "I am a stranger."
He nodded and seemed to understand.
"Have you seen any other strangers in this island of yours?" I asked.
He seemed a little confused.
"No, no," he began, and then altered it into "Yes, yes."
Which did he mean, or did he mean anything at all.
"A man in an oilskin coat, with a moustache on his lip—here," I went on, touching my own lip. "Who goes out at night and walks along the shore; have you seen any one like that?"
