Night Watch

Est,’” said Vimes. “Shouldn’t it say when you were established?”
    “Should it?” Dibble looked down at his tray.
    “How long have you been going?” said Vimes, selecting a pie.
    “Let’s see…what year is this?”
    “Er…Dancing Dog, I think.”
    “Since Tuesday, then,” said Dibbler. His face brightened. “But this is only the start, mister. This is just to get a stake together. In a year or two I’m going to be a big man in this town.”
    “I believe you,” said Vimes. “I really do.”
    Dibbler looked down at his tray again as Vimes strolled off. “Cutting my own throat, cutting my own throat,” he mumbled to himself, and seemed to like the sound of it. But then he focused more clearly on the tray and his face went pale.
    “Sergeant!” he shouted. “Don’t eat the pie!”
    Vimes, a few yards away, stopped with the pie halfway to his mouth.
    “What’s wrong with it?” he said. “Silly me. I mean, what’s uniquely wrong with it?”
    “Nothing! I mean…these are better!”
    Vimes risked another look at the tray. They all looked the same to him. Dibbler’s pies quite often looked appetizing. Therein lay their one and only charm.
    “I can’t see any difference,” he said.
    “Yeah, yeah, there is ,” said Dibbler, sweat beading on his forehead. “See? The one you got has that little pattern of pastry pigs on it? And all the others have pastry sausages? I’d hate for you to think that, you know, I thought you were a pig or anything, so if you’ll hand it over I’ll happily give you, er, another one, that one’s not the right one, er, not that it’s a wrong one, but, er, with the pig and everything…”
    Vimes looked into the man’s eyes. Dibbler had yet to learn that friendly blankness that thirty years of selling truly organic pies would call into being.
    While the man stared in horror, he took a large bite out of the pie.
    It was everything that he had expected and nothing that he could identify.
    “Yum,” he said, and, with some concentration, eyes fixed on the luckless pieman, finished it all.
    “I think it’s quite possible no one else makes pies like you do, Mr. Dibbler,” he said, licking his fingers in case he might want to shake hands with someone later on.
    “You ate it all?” said Dibbler.
    “Was that wrong?” said Vimes.
    And now relief rose off the man like smoke off a greenwood fire.
    “What? No! That’s fine! Jolly good! Want another one to help it down? Half-price?”
    “No, no, one is more than enough,” said Vimes, backing away.
    “You finished every bit?” said Dibbler.
    “That was right, wasn’t it?” said Vimes.
    “Oh, yeah. Sure. Obviously!”
    “Got to be going,” said Vimes, moving on down the lane. “I’ll look forward to seeing you again when I’ve got less appetite.”
    He waited until he was well out of sight before taking a few random turns in the network of alleys. Then he stepped into the shadow of a deep doorway and felt in his mouth for the piece of pie that had seemed curiously unchewable even by pie standards.
    Usually, if you found something more-than-usually hard or crunchy in one of Dibbler’s Famous Pork Pies, the trick was either to swallow it and hope for the best or spit it out with your eyes closed. But Vimes felt around between gum and cheek and fished out a folded piece of paper, stained with unknowable juices.
    He unfolded it. In smudged pencil, but still readable, it read: Morphic Street, 9 o’clock tonight. Password: swordfish.
    Swordfish? Every password was “swordfish”! Whenever anyone tried to think of a word that no one would ever guess, they always chose “swordfish.” It was just one of those strange quirks of the human mind.
    That explained the guilt, anyway. A plot. Another damn plot, in a city full of plots. Did he need to know about plots? Anyway, he knew about this one. Morphic Street. The famous Morphic Street Conspiracy. Ha.
    He pushed the greasy scrap into a pocket and then hesitated.
    Someone was being quiet. Overlaid on the distant street noises was a sort of hollow in the sounds, filled by careful breathing. And the hairs on the back of his neck were standing up.
    Quietly, he pulled the blackjack out of his rear pocket.
    Now, what were the options? He was a copper, and someone was creeping up on him. If they weren’t a copper, then they were in the wrong (because he was a copper). If they were a copper, too, then they were one of Swing’s crew and therefore in the wrong
