Beyond exhibiting his credentials, Marks made no effort to explain why the ship was under suspicion. He watched the deck closely to prevent the crew from throwing packages overboard, and as soon as they reached dock he requested all officers to join him in one of the big rooms belonging to the Customs Service. There he explained his reasons for believing that some one on board was guilty of defrauding the government out of duty on a number of uncut diamonds.

"What's more," he concluded, at the end of an address which was purposely lengthy in order to give his men time to search the ship, "I am willing to stake my position against the fact that two more diamonds are on board the ship at this moment!"

The captain, pompous and self-assertive, preferred to rise and rant against the "infernal injustice of this high-handed method."

To his amazement, the other started back as if he had been struck, and then, recovering himself, muttered: "No, thanks. I'm not smoking."

"Not smoking?" was the thought that flashed through Marks's head, "then why—"
