Molly spread the blueprint across the hood of the van. It was a crayon drawing of a lopsided bouncy castle. "Where did you get this?" Bill asked. "The birthday girl drew it. Her mum posted it online. Her security is shocking." Bill squinted at it. "Why is the guard a purple dinosaur?" "That's the entertainer. Gerald. Forty minutes of balloon animals, then a nap in his car. That's our window." Rain drummed on the van roof while Bill chewed his thumbnail, the way he always did before a job went sideways. He had once fled a jewellery store because a parrot said hello. "And the presents?" "Stacked by the trampoline. Thirty boxes, give or take. I'll go in as a clown." "And what exactly do I go in as?" Molly handed him a folded bundle of pink tulle. Bill held it up and watched a sequined wand fall into his lap. "A fairy godmother," she said. "Nobody questions a fairy godmother." "Children question everything, Molly. Everything." "Then you grant wishes until I'm done." Bill stared at the wand, then sighed and tucked it into his belt beside the bolt cutters. "If anyone asks for a pony, I'm aborting the mission."
