Molly studied the glittering birthday invitation like it was a bank blueprint. “We enter disguised as clowns, locate the presents, and escape before anyone notices.” Bill adjusted his enormous red shoes. “I object to the word disguised. I am naturally this alarming.” “You’re wearing a tutu.” “It brings out my knees.” They crouched behind the hedge, watching children swarm around a cake shaped like a dinosaur. Inside, balloons bobbed, parents chatted, and a mountain of wrapped gifts waited beside the sofa. Molly whispered, “Phase One: blend in. Phase Two: distract the adults. Phase Three: carry the presents to the van.” “Phase Four?” “Celebrate our success with stolen cupcakes.” “I support this operation.” They slipped through the gate, juggling rubber chickens. A little girl pointed at Molly’s painted moustache. “Are you entertainers?” “Absolutely,” Molly said. “We specialize in invisible magic.” Bill grabbed a microphone. “Behold! I shall make this entire room disappear!” The children cheered. The adults turned toward him, fascinated and mildly concerned. Molly stacked presents beneath a tablecloth while Bill performed a dance that appeared to injure several joints. Suddenly, the birthday boy approached. “Are you taking my presents?” Molly froze. Bill bowed. “Taking? No. We’re relocating them for security.” “From what?” “Unsupervised clowns,” Molly said. The boy considered this, then nodded solemnly. “Good plan. Put them in my room.” The thieves exchanged glances. Their criminal career had acquired a tiny manager.
