"Listen carefully, my dear, and you'll know more about the ways of the navy that guards your coasts than you did before. When men are allowed on shore at Malta, the owner has a fancy to see them snugly on board again at a certain reasonable hour. After that hour any Maltese policeman who brings them aboard gets one sovereign, cash. But he has to do all the bringing part of it on his own. Consequence is, you see boats rowing out to the ship, carrying men who have overstayed their leave; and, when they get near enough, the able-bodied gentleman in custody jumps to his feet, upsets the boat, and swims to the gangway. The policemen, if they aren't drowned—they sometimes are—race him, and whichever gets there first wins. If it's the policeman, he gets his sovereign. If it's the sailor, he is considered to have arrived not in a state of custody, and gets off easier. What a judicious remark that was of the Governor of North Carolina to the Governor of South Carolina! Just one more cup, please, Phyllis."

"But how does all that apply?" I asked, dry-mouthed.

"Why, Hawk upset the professor just as those Maltese were upset. There's a patent way of doing it. Furthermore, by judicious questioning, I found that Hawk was once in the navy, and stationed at Malta. Now, who's going to drag in Sherlock Holmes?"

"You don't really think—" I said, feeling like a criminal in the dock when the case is going against him.

"I think friend Hawk has been reënacting the joys of his vanished youth, so to speak."

"He ought to be prosecuted," said Phyllis, blazing with indignation.

Alas, poor Hawk!

"Nobody's safe with a man of that sort hiring out a boat."

Oh, miserable Hawk!

"But why on earth," I asked, as calmly as possible, "should he play a trick like that on Professor Derrick, Chase?"
