Molly pressed her back against the garden fence and peered through a gap in the wooden slats. Inside, eleven sugar-hyped children screamed and chased each other around an inflatable unicorn. "There must be forty presents in that pile," she whispered, adjusting her black beanie. Bill squinted through his own gap. "I count forty-three. I've been watching for twenty minutes." "That's not surveillance, that's just being weird." "It's called dedication." He pulled out a hand-drawn map of the backyard. "We go in through the gate during musical chairs. Everyone looks left during musical chairs." Molly grabbed the map and studied it. "You've labeled the bouncy castle as a hostile zone." "A kid bit me there last Easter. I don't forget." A balloon popped inside and both of them flinched simultaneously. "We grab the presents, we're gone before the cake comes out," Molly said, steadying herself. "What if they sing Happy Birthday slowly? Some families really drag that out." "Then we suffer through it like professionals." Bill nodded gravely and rolled up his map. A child's face suddenly appeared at the fence gap, staring directly at them. "Hello," said the child. "Run," said Molly.
