difficult to break."

    As soon as Arkady was alone in Pribluda's flat he went to the office and opened the computer, which immediately demanded the password. An access code that combined up to twelve letters and numbers was virtu ally unbreakable, but a code also had to be remembered, and this was where the humans Arkady knew tended to use their birthday or address. Arkady tried the names of the colonel's wife, son, saint (although Pribluda was an atheist, he had always enjoyed a bottle on his saint's name day), favorite writers (Sholokhov and Gorky), favorite teams (Dynamo and Central Army). Arkady tried 06111968 for the date of Pribluda's Party membership, a chemical C12H22011 for sugar, a homesick 55-45-37-37 for the coordinates (latitude and longi tude, minutes and seconds) of Moscow . He tried words written and transposed into numbers (even though the correct order of the Russian alphabet was a matter of controversy heading into the twenty-first century). The computer fan would buzz for a moment, then purr along. He tried until he traded the glow of the machine for the dark of the balcony, where he took solace in the steady sweep of the lighthouse beam and the deep insomnia of the night.
    Arkady discovered he fostered a killer's calculation   hat even if his story was implausible, the truth was no more plausible. He was also a little bemused by his own reaction to the attack. He had defended himself instinctively, the way a man about to dive resists being pushed.
    He had no idea why he had been attacked except that it had to do with his friend Pribluda. Not that Pribluda was a friend in the ordinary sense. They shared no tastes, interests, politics. In fact, truth be told, Pribluda was in many ways a terrible man.
    Arkady could imagine him now bringing out the vodka and saying, "Renko, old pal, you're fucked. You are in a crazy country, in a foreign land where you know nothing, including the language." Pribluda would hunch forward to touch glasses and grin that ghastly smile of his. He had the habit of loosening a button, a collar, a cuff with each glassful, as if drinking was serious work.» All you can be sure of is that you know nothing. No one will help you because of your brown eyes. Everyone who steps forward as a friend will be an enemy. Everyone who offers to help is hiding a knife behind his back. Cheers!" The colonel would make a grand gesture of throwing the vodka's cap into the sea. That was his idea of panache.» Do you appreciate logic?"
    "I love logic," Arkady might say.
    "This is logic: Rufo had no reason to kill you. Rufo tried to kill you. Ergo, someone sent Rufo. Ergo, that someone will send someone else."
    "A nice thought. Was that a present to take home?"
    Arkady would nod in the direction of the man-sized doll brooding in the corner. The way its shadow shifted when the breeze pushed the lamp was a bit unnerving.» Charming." He fished from his coat a piece of note-paper on which he had written Rufo's address and the house key he had lifted off the body before Luna arrived.
    "What I think you should do," Pribluda would steamroll on, "is lock yourself with a gun and oranges, bread and water in a room at the embassy, maybe a bucket for personal needs, and don't open the door until you go to the airport."
    In his mind, Arkady asked, "Spending a week in Havana hiding in a room, wouldn't that be a little perverse?"
    "No. Killing Rufo when you were going to kill yourself, that's perverse."
    Arkady went down the hall to the office and returned with a map of the city that he spread under a lamp.
    "You're leaving?" Pribluda was always horrified when Arkady quit before the bottom of the bottle.
    Arkady searched for a street called Esperanza and wrote down Rufo's address on a piece of paper. He thought, I'm not just going to sit and wait. I also have your car key. If you want to help, tell me where the car is. Or give me your code.
    Pribluda's ghost, insulted, disappeared. Arkady, on the
