“Well, as I was saying—because of that and some other business, Uncle Sam knew that I could pilot a plane. Six weeks ago I was called to Washington and told that an international gang of criminals were flooding this country with diamonds, stolen in Europe. What the officials didn’t know was the method being used to smuggle them into this country. However, they said they had every reason to believe that the diamonds were dropped overboard from trans-Atlantic liners somewhere off the coast and picked up by the smugglers’ planes at sea. My job was to go abroad and on the return trip, to keep my eyes peeled night and day for airplanes when we neared America.”
“Did you go alone?”
“Yes, but I gathered that practically every liner coming over from Europe was being covered by a Secret Service operative. I made a trip over and back without spotting a thing. On the second trip back, something happened.”
“When was that?”
“Night before last. The liner I was aboard had just passed Fire Island lightship. I stood leaning over the rail on the port side and I saw half a dozen or more small boxes dropped out of a porthole. They seemed to be fastened together. Once in the water, they must have stretched out over a considerable distance. Of course, there are notices posted forbidding anyone to throw anything overboard: and there are watchmen on deck. But they can’t very well prevent a person from unscrewing a porthole and shoving something out!”
“Did you report it?”
“You bet. The skipper knew why I was making the trip. We located the stateroom and found that it belonged to three perfectly harmless Y.M.C.A. workers who were peaceably eating their dinner at the time. Somebody slipped into their room and did the trick.”
“Did you hear or see any plane?”
“I thought I heard a motor, but it didn’t sound like the engine of a plane. I couldn’t be sure.”
“The motor sailor, probably?”
