Molly spread the crayon-drawn map across the hood of the rusty van and tapped it with a gloved finger. The target was a modest suburban house with pink balloons tied to the mailbox. "The bouncy castle goes up at two," she said. "That's our window." Bill squinted at the map. Several rooms were labeled with smiley faces. "Did you draw this yourself?" "The kid left it in the park. Seemed useful." "It says the cake is guarded by a dragon." "That's the family dog. A labradoodle." Bill pulled his balaclava down nervously. The sound of children singing drifted over the fence, off-key and relentless. "There could be thirty kids in there," he whispered. "Thirty kids who aren't paying attention to the present table," Molly whispered back. "What if they're armed with party poppers?" "Bill, they're seven years old." "Seven-year-olds are wildly unpredictable. My nephew bit a postman." Molly rolled up the map and stuffed it firmly in her jacket pocket. "We go in, we grab the presents, we're out before they sing Happy Birthday. Simple." Bill looked at the balloons swaying cheerfully in the breeze. "Nothing about this is simple." "That's why they call it a heist."
