Molly crouched behind the garden hedge, her black turtleneck already attracting suspicious glances from the postman. She adjusted her oversized sunglasses and consulted the hand-drawn map spread across her knees, which depicted, in alarming detail, the layout of a six year old's birthday party. Bill belly-crawled through the flower bed, leaving a trail of crushed petunias behind him. He had insisted on wearing camouflage trousers, which made him entirely invisible in a jungle environment but catastrophically obvious on a suburban lawn in Swindon. "There are more children than expected," Molly whispered. Bill pulled a pair of binoculars from his vest and surveyed the scene. A clown was making balloon animals near the back fence. A bouncy castle wobbled ominously in the breeze. The presents were stacked in a magnificent glittering pile beside the garden table, wrapped in paper so bright it was practically taunting them. He had underestimated the security. Three grandmothers sat in lawn chairs forming what appeared to be an impenetrable perimeter. "The grannies are the problem," Bill muttered. They watched in silence as one grandmother produced knitting needles from her handbag, wielding them with the quiet menace of someone who had seen considerably worse than thieves.
