the second guy said. “Were there more boxes?”
    “That was the best one. Depends if Mrs. Jacob is big or small, I guess.”
    “Depends if she’s finished by tonight.”
    “You got any doubts on that score? The mood he’s in today?”
    They strolled together to a different slot and unlocked a black Chevy Tahoe. Little brother to the Suburban, but still a giant vehicle.
    “So where is she?” the second guy asked.
    “A town called Garrison,” the first guy said. “Straight up the Hudson, a ways past Sing Sing. An hour, hour and a half.”
    The Tahoe backed out of the slot and squealed its tires on its way around the garage. Bumped up the ramp into the sunshine and headed out to West Street, where it made a right and accelerated north.

    WEST STREET BECOMES Eleventh Avenue right opposite Pier 56, where the westbound traffic spills out of Fourteenth Street and turns north. The big black Tahoe was caught in the congestion and added its horn to the frustrated blasts cannoning off the high buildings and echoing out over the river. It crawled nine blocks and made a left at Twenty-third Street, then swung north again on Twelfth. It got above walking speed until it passed the back of the Javits Convention Center, and then it got jammed up again in the traffic pouring out of West Forty-second. Twelfth became the Miller Highway and it was still solid, all the way over the top of the huge messy acreage of the old rail yards. Then the Miller became the Henry Hudson Parkway. Still a slow road, but the Henry Hudson was technically Route 9A, which would become Route 9 up in Crotonville and take them all the way north to Garrison. A straight line, no turns anywhere, but they were still in Manhattan, stuck in Riverside Park, a whole half hour after setting out.
    IT WAS THE word processor that meant the most. The cursor, patiently blinking in the middle of a word. The open door and the abandoned bag were persuasive, but not critical. Office workers usually take their stuff and close their doors, but not always. The secretary might have just stepped across the hall and gotten involved in something, a quest for bond paper or a plea for help with somebody’s copying machine, leading to a cup of coffee and a juicy story about last night’s date. A person expecting to be absent two minutes might leave her bag behind and her door open and end up being gone a half hour. But nobody leaves computer work unsaved. Not even for a minute. And this woman had. The machine had asked him DO YOU WANT TO SAVE THE CHANGES? Which meant she had gotten up from her desk without clicking on the save icon, which is a habit just about as regular as breathing for people who spend their days fighting with software.
    Which put a very bad complexion on the whole thing. Reacher was through in Grand Central’s other big hall, with a twenty-ounce cup of black coffee he had bought from a vendor. He jammed the lid down tight and squeezed the cash roll in his pocket. It was thick enough for what he was going to have to do. He ran back and around to the track where the next Croton train was waiting to leave.
    THE HENRY HUDSON Parkway splits into a tangle of curling ramps around 170th Street and the north lanes come out again labeled Riverside Drive. Same road, same direction, no turn, but the complex dynamic of heavy traffic means that if one driver slows down more than the average, then the highway can back up dramatically, with hundreds of people stalled way behind, all because some out-of-towner a mile ahead became momentarily confused. The big black Tahoe was brought to a complete halt opposite Fort Washington and was reduced to a lurching stop-start crawl all the way under the George Washington Bridge. Then Riverside Drive broadens out and it got itself up into third gear before the label changed back to the Henry Hudson and the traffic in the toll plaza stopped it again. It waited in line to pay the money that let it off the island of Manhattan and away north
