Molly spread the crayon-drawn map across the sticky diner table, her eyes gleaming with determination. "The target is heavily fortified," she whispered. "We're talking balloon arches, streamers, possibly a bounce house perimeter." Bill squinted at the crude drawing. "Is that a dinosaur or a security guard?" "That's the birthday boy's mother. She's the real threat. Woman has eyes like a hawk and the reflexes of a caffeinated squirrel." "What's our window?" "Cake time. Everyone gathers around for the singing. We'll have exactly ninety seconds while they butcher Happy Birthday in three different keys." Bill nervously tapped his coffee cup. "And the presents?" "Stacked on a folding table near the garage door. Seventeen wrapped packages, mostly rectangular. I'm betting heavy on LEGO sets." "I don't know, Molly. These are children. Innocent children." "Innocent? Billy, my nephew Chad is attending this party. That little monster glued my car keys to a hamster last Thanksgiving." Bill considered this, nodding slowly. "Fair point. What about the clown?" "Already handled. I promised him double his rate to distract everyone with balloon animals." "You're a genius." "I know. Now eat your pancakes. We've got a heist to execute."
