"Well," I said slowly, "if there were any sort of certainty about it not being absolutely a wild goose chase...."
"You'd go after it, eh?"
"It'd be a devilish amusing way of finishing up my leave."
John Bard smiled indulgently.
"It might be more exciting than amusing," he said, "if Black Pablo has anything to do with this affair."
"Do you think there is anything in it?" I asked.
"In the latter stages of the war," my host replied, "I heard vague rumours about some island off the coast where German commerce-raiders used to rendezvous for supplies. But I never heard this island named. It seems to me that the first thing to be done is to see your friend, Adams, again. After all, he's been to the island. He might be able to tell us more about it. Besides...."
He broke off and flicked the ash from his cigar. His manner had suddenly become rather grave.
"Besides what?" I demanded.
"If Black Pablo and his friends are after that plan or whatever it is, Adams is in pretty considerable danger."
