Molly crouched behind the hedgerow, peering at the bouncing castle where shrieking children ricocheted like over-caffeinated pinballs. Bill knelt beside her, adjusting his comically oversized clown wig. “This is insane even for us,” Molly whispered, checking her watch. “They’ve got a piñata the size of a Mini Cooper.” Bill grinned beneath his fake mustache. “That’s why we strike at peak cake o’clock. When they’re all singing Happy Birthday, we slip in the back, swap the presents for our decoy bags, and vanish like sophisticated ninjas.” “Sophisticated ninjas don’t wear squeaky shoes, Bill.” “These are authentic. Helps sell the clown alibi. Besides, you said we needed to think outside the box. What’s more outside the box than stealing from children at their own party?” Molly sighed. “We’re going to hell.” “Probably. But we’ll arrive in a van full of Xbox consoles and miniature bicycles. Think of the resale value.” A fresh chorus of Happy Birthday erupted from the garden. Molly checked her bag of fake gifts and nodded grimly. “Fine. But if we get recognized by a six-year-old, I’m throwing you under the bouncy castle.”
