The rain drummed against the bounce house as Molly and Bill crouched behind a hedge, eyeing the glowing windows of the Henderson birthday party. Inside, a clown juggled flaming torches with alarming confidence. Stacks of wrapped presents gleamed beneath the chandelier like treasure. Molly checked her watch. "Remember the plan. In, grab the loot, out before the cake." Bill nodded, hefting a sack big enough to hold a small pony. "Right. Nobody notices two adults sneaking past the punch bowl." They slipped through the side gate, dodging a wobbling inflatable dinosaur and a tray of suspiciously green cupcakes. Molly reached the gift table first and scooped up an armful of boxes. One of them rattled loudly, and Bill froze, clutching the sack to his chest. A small boy in a paper crown turned around, blinked at them, and offered Bill a juice box. "Thanks," Bill mumbled, taking it with a sheepish grin. Molly groaned from the cake table, already halfway into a frosting-covered loot bag, while the children began chanting for the magician to come back out.
