Molly crouched behind the hedge, staring at the pastel explosion of balloons and streamers spilling out of Mrs. Pritchard’s garden. Children shrieked with sugar-fueled joy while a clown on stilts wobbled near the cake table, apparently held together by helium and optimism. Bill adjusted his black gloves, which were so cheap they squeaked. “Simple job,” he whispered. “We slip in, grab the presents, and vanish.” Molly eyed the gift mountain by the conservatory. “You say that every time.” “And every time, we’re in and out before anyone knows.” “Last time,” she said, “we were chased by a miniature pirate on a tricycle.” Bill frowned. “That was a fluke.” A tiny voice suddenly shouted, “The piñata’s gone missing!” and the crowd surged toward the back lawn. The two thieves froze as a toddler in a fairy costume waddled past dragging a ribbon wand like a sabre. Molly grinned. “Perfect distraction.” Bill gave the gazebo a quick look. “You take the left side. I’ll cover the presents.” “And if there’s a saxophone?” He winced. “We never speak of the saxophone.” Together they slipped through the roses, blending into the chaos of cake, confetti, and laughter, two professionals on a mission only slightly complicated by the fact that the party’s security consisted of a confused bouncy castle and seventeen sugar-high seven-year-olds.
