red-lacquered fingernail across the stamp. Then she stuck the fingernail in her mouth, which was just a narrow crack in her taut face. She smacked her lips. And then both her eyebrows shot up.
âWell, shiver my timbers,â she whispered.
âHuh?â Nilly said.
âIâll buy it. How much do you want for it?â
âNot much,â Nilly said. âJust enough for the plane tickets to ⦠Ouch!â
He shot an irritated look at Lisa, who had kicked him in the shin.
âSeven hundred dollars,â Lisa said.
âYou cat-oâ-nine-tails!â the woman shouted in outrage. âSeven hundred for a stamp with a picture of a dreary, dead French president?â
âOkay, five hundrââ Nilly started, but yelped as he was kicked in the shin yet again.
âSeven hundred, right now. Otherwise weâre leaving,â Lisa said.
âFive hundred plus a clock for each of you,â the woman said. âFor example, this clock that runs slow. Specially made for people who have too much to do. Or this one that runs fast, for people who are bored.â
âYes!â Nilly cried.
âNo!â Lisa said. âSeven hundred. And if you donât accept in the next five seconds, the price goes up to eight hundred.â
The woman gave Lisa a look of rage. She openedher mouth, about to say something, but stopped when she saw the look on Lisaâs face. Then she sighed, rolled her eyes and spit out a resigned, âFine, you keelhauling, barnacle-baiting urchin.â
The woman disappeared behind the curtain on her roller skate and returned with a wad of cash, which she handed to Nilly. He licked his right thumb and started counting the bills.
âI hope you can add,â the woman mumbled.
âSimple math,â Nilly said. âTwenty-five twenties plus two old hundred dollar bills. Thatâs seven hundred. Thank you for your business, Miss â¦?â
âMy nameâs Raspa,â the woman said, with a thin, cautious smile, as if she were afraid her face would rip if her smile were any bigger.
âAnd what are your names, my dear children?â
âNilly and Lisa,â Nilly said, and handed the money to Lisa, who stuffed it into a pocket in her school knapsack.
âWell then, Nilly and Lisa, Iâll throw in these gold watches.â
She dangled two gleaming watches in front of them.
âCool!â Nilly said, grabbing for one of them, but Raspa pulled it back again.
âFirst I have to set the time for the time zone youâre going to,â she said. âSo where are you headed?â
âParis!â Nilly gushed. âThe capital of France ⦠Ouch!â
His eyes bulged from the pain.
âOh, Iâm sorry. Did I hit your leg?â Lisa asked. âLet me see it. Did I leave a bruise?â
She leaned over toward Nilly and snarled softly into his ear so that Raspa couldnât hear, âThe postcard warned us not to say anything about where we were going!â
âSo sue me,â Nilly mumbled crossly.
âAh, Paris,â the woman sneered, showing a row of sharp white teeth. âI was there once. A lovely city.â
âNah, itâs not that great,â Nilly grunted, rubbing his leg. âActually, we changed our minds. Weâre not going there after all.â
âReally? Why not?â Raspa laughed hoarsely.
âToo dangerous. I hear the rivers in Paris are full of soggy, wet, venomous platypuses shaking water all over people.â
Raspa leaned down closer to Nilly and breathed her rotten-meat-and-stinky-sock-breath on him, âWell, then, good thing these gold watches are watertight.â
âW-w-watertight?â said Nilly, who had never ever stuttered before in his whole life.
âYes,â Raspa whispered, so softly that they could hear all the clocks in the shop ticking. âWhich means that you can swim underwater with them. And wear them in the
