Rain stitched silver lines across the bakery window, where Molly spread a map of the neighborhood beside two cooling cinnamon rolls and one suspicious raisin. “Bill, the invitation says the birthday party has forty children, a magician, and enough presents to make our pension plan look respectable for once, perhaps.” Bill examined the map upside down, then rotated it until the bakery occupied the ocean and the school floated near a mysterious legend of dragons. “Excellent. If we arrive by submarine, nobody will suspect a thing, except the children, who are famously observant and armed with juice boxes at parties.” Molly tapped the party address, which was the community hall, a cheerful building with painted balloons and a sign reading WELCOME, GROWNUPS in several colors. “Here’s my strategy: we enter as entertainers, distract everyone with a tasteful routine, then leave carrying every gift beneath our dignity and our matching hats.” She produced two paper crowns from her coat. One had glittery stars; the other said Birthday Princess, though Bill wore it without complaint or fuss. “Why am I Princess?” “Because you have the posture.” “I have the posture of a damp umbrella.” “An elegant damp umbrella.” Outside, a passing child dragged a balloon shaped like a dinosaur. Bill flinched, and the balloon bobbed after him like an unpaid debt, smiling maliciously. “Children detect fear.” “Then I shall look fearless,” Bill whispered, tightening his crown. “You look like royalty facing a tax audit in a thunderstorm, perhaps.” Molly circled the word ALL on her napkin, then crossed it out and wrote MOST, then MAYBE NONE, as her expression softened like warm butter. “Wait. Those gifts are for children. We could take the cake instead.” “That seems less lucrative and more crumbly than expected.” From the hall came a burst of children’s laughter, followed by applause. Molly listened, looking like someone remembering her own birthday fondly from long ago. “We’re thieves, not monsters.” “The distinction is important, though your crown is committing a separate crime against public taste and several mirrors in every town.” He folded the map into a paper boat, perhaps surrendering to geography. It sailed one inch across the table and capsized in cinnamon without warning. “New plan. We go inside, announce ourselves, and offer to perform a magic trick.” “Can we vanish before the cake arrives without any witnesses ever?” At the hall, a volunteer opened the door before they could knock. She mistook their crowns for costumes and handed them tambourines with a smile. “Are we expected to steal anything?” “Only the show.” “Then let’s steal the show and leave everything else where it belongs, and act like professionals.” By the finale, Bill juggled oranges while Molly performed a trick with a handkerchief and one patient rabbit borrowed from the magician for the occasion. “Your payment is applause and leftover cake.” “We accept both, though the cake’s security seems unusually lax tonight, with gratitude and without any suspicious questions.”
