The Wheel of Darkness by Douglas Preston, Lincoln Child

board this ship and only seven days in which to find the murderer and retrieve the Agozyen.”
    “Is that the passenger list?”
    Pendergast nodded. “Direct from the ship’s database. Including occupation, age, sex, and time of boarding. As I told you earlier, I’ve already ruled out members of the crew.”
    “How did you obtain that?”
    “With great ease. I located a low-level computer maintenance tech and told him I was a North Star auditor, evaluating crew performance. He couldn’t furnish the list quickly enough. I’ve already made considerable progress thinning the pool of suspects.” And he pulled a sheet of paper from his jacket pocket.
    “Go on.”
    A long white finger touched the paper. “The murder was committed at ten, the cab arrived at the dock at half past midnight, and so the killer must have boarded after that point. That alone removes one thousand four hundred seventy-six names.”
    The finger touched the paper again. “The murderer is a man.”
    “How in the world do you know that?” asked Constance, as if the assumption were an offense to womanhood.
    “The bottle of scotch. A man like Ambrose would hardly have chosen that if his visitor were a woman. And then there is the knife that was driven clean through the body, through half an inch of carpet, and almost an inch into plywood flooring. That must have taken great strength. Finally, Ambrose himself was a mountain climber in superb physical condition, not an easy man to kill. It implies our killer is strong, fit, and fast—and male.”
    “I’ll concede the point.”
    The finger moved down the sheet. “For these same reasons, we can bracket the age: over twenty, under sixty-five. On a ship like this, that latter fact is most useful. In addition, he’s not traveling with a wife: the messy murder, cab ride, disguise, boarding ship with the Agozyen—all these are the actions of a man unencumbered by a wife. The psychopathology of the murder, the keen pleasure taken in the violence, also points strongly toward a single man. A single male, of a certain age: one thousand and twelve more names removed. Which gives us two hundred and twelve left.”
    The finger moved again. “All the evidence shows that Ambrose contacted a known collector, perhaps not of Asian antiquities per se, but a collector nonetheless. And a man whose face might be recognizable to members of the general public. Which leaves us with twenty-six.”
    He glanced up at Constance. “The murderer is clever. Put yourself in his shoes. He has to get this awkward box on board ship without being conspicuous. He would not have boarded immediately, carrying the box—that would be remembered. And besides, he was covered with blood from the murder; he’d have to change his clothes and wash up in a secure place. So what would he do?”
    “Go to a hotel room, wash, repack the Agozyen in a larger steamer trunk, and then board at the height of the final crush.”
    “Precisely. And that would be around nine this morning.”
    Constance smiled wryly.
    The finger lifted from the paper. “Which leaves us with just eight suspects—right here. You’ll note a curious coincidence: two were at our table.” He pushed the paper over. She read the names:
