Molly pressed her back against the brick wall and peered around the corner at the bouncy castle. A banner reading "Happy 7th Birthday Tyler!" flapped in the breeze like a taunt. "The presents are stacked near the picnic table," she whispered, adjusting her balaclava. Bill squinted through tiny binoculars shaped like a duck. "I count at least thirty packages. Maybe forty." "We go in during the cake song," Molly said. "Everyone looks at the cake during the cake song." "What if they have a clown?" Bill asked, his voice cracking slightly. "Why would a clown be a problem?" "Clowns are unpredictable, Molly. Everyone knows that." She grabbed his collar. "You robbed the National Museum of Art twice." "That museum didn't have a clown." Molly released him and exhaled slowly. A chorus of tiny screaming children erupted from the garden as someone unleashed a piƱata. Both thieves flinched. "Maybe we should rob a bank instead," Bill offered. "Banks have security cameras." "And this has forty-seven children armed with party poppers." Molly checked her watch. The cake song was starting. She cracked her knuckles. "Let's move."
