Molly spread the crayon-drawn map across the hood of the van. "The bouncy castle's here," she said, tapping a lopsided blue blob. "Cake table, here. Presents, stacked by the piñata." "How many kids?" Bill asked. "Twenty-two. Plus mothers." "Mothers." Bill exhaled through his teeth. "Mothers are worse than dogs, Moll. Dogs you can bribe." "Which is why you're going in as the clown." "Absolutely not." "You've got the shoes." "I have the shoes because of an unrelated incident." Molly ignored him and drew a red arrow across the patio. "You do balloon animals for eleven minutes. Long enough for me to walk out the side gate with the loot bag." "And when the birthday boy wants a giraffe?" "Give him a snake. Nobody can tell." Bill studied the map, scratching his jaw. A distant, terrible sound of children reached them from over the fence — shrieking, joyous, feral. "There's no honor in this," he said quietly. "There's a PlayStation in there, Bill. Two of them. Rich kid, divorced parents, competitive gift-giving." He was silent for a long moment. "Fine. But I'm keeping the tricycle." "Deal." "And if anyone cries," Bill said, tugging on the red nose, "we abort." Molly patted his cheek. "You sentimental fool."
