A note arrives every night, signed with a number. Not one of them has ever lied to you.

THE DATE IS SET. THE NAME IS NOT.

December 1938. The liner Aurora leaves Le Havre for New York with two hundred and forty passengers and crew aboard and one letter locked in the purser's safe. Someone on the passenger list has promised to sink her on the night of December 24. The company will not turn back. There is too much money in the hold.

The investigator they hired was killed on the dock the night before sailing.

You are traveling under his name, listed as a traveling salesman in hardware with sample trunks stowed below. You have twenty-four days, and you have the manifest: every passenger, every crewman, all two hundred and forty lines, printed to be marked up.

Every day at sea hands you a document. A laundry register. A ship's log. Eight witness statements that contradict each other. A telegram from London. Not one of them gives you a name. Every one of them shortens your list.

On Christmas morning, one line should be left.
