Molly crouched behind the garden hedge, her black turtleneck already itching in the afternoon heat. She peered through the leaves at the birthday party unfolding in the backyard, watching six-year-olds hurl cake at one another with gleeful abandon. The pile of wrapped presents on the gift table was enormous, a glittering mountain of ribbons and shiny paper that practically sang to her professional instincts. Bill crawled up beside her, snapping three twigs loudly in the process. He was wearing sunglasses despite the cloud cover and had inexplicably brought a briefcase. "The presents," Molly whispered. Bill nodded gravely. "Tonight." She studied the layout with practiced eyes. The bouncy castle provided cover on the eastern flank. A distracted clown was fumbling balloon animals near the fence. Parents clustered around the drinks table, increasingly desperate looking. The birthday child, one Magnus Pembrook-Hayes, sat in his throne-like chair wearing a paper crown, surveying his kingdom with the casual cruelty only a six-year-old can project. Molly pulled out her notepad and sketched the scene. This would require timing, precision, and an exit strategy that accounted for at least one inevitable tantrum, probably from Bill.
