Rain needled the bakery awning while Molly and Bill crouched behind a stack of wobbling milk crates, studying the village hall through a fogged pair of opera glasses that had probably once belonged to someone richer and deader. Inside, balloons bobbed against the ceiling like captive moons, and a clown in huge shoes wrestled a ribbon onto a chair with the tragic dignity of a failed admiral. Molly unfolded a hand-drawn map on her knee. It was mostly arrows, crumbs, and confidence. Her eyes glittered at the sight of a mountain of brightly wrapped gifts piled beside a banner that read HAPPY SEVENTH, OSCAR, in letters so cheerful they felt personally insulting. “Cake at three, chaos at four,” she whispered. Bill adjusted his flat cap and peered through the rain. “And presents at four-oh-one.” They watched parents troop in carrying casseroles, toddlers, and the exhausted smiles of civilians entering a war zone. The hired magician arrived next, lugging a top hat and an expression that suggested rabbits had wronged him professionally. Molly tapped the window schedule she’d memorized. When the pass-the-parcel riot began, Bill would slip in dressed as a balloon man, she as an aunt from Leeds. They’d sweep the gifts into a laundry trolley and roll them out the side door. A child inside screamed with joy. Bill grinned. “Our kind of alarm.”
