Molly tapped her fake mustache. “Bill, the children's party starts at noon. We go in disguised as entertainers, steal the presents, and leave before anyone asks us to sing.” Bill lifted the bear head. “Excellent. I’ll be the magician.” “You can’t do magic.” “You once pulled a rabbit from a hat.” “It was a sock, Bill.” “A very convincing sock.” “Honestly.” “I can make a sandwich disappear.” “That was lunch.” “Exactly. The audience was stunned.” “You’ll wear this bear suit.” “Why is it wearing sunglasses?” “Because every professional thief needs a brand.” “And you?” “Clown.” “Your disguise is just your normal personality.” “Remember, no stealing from the goodie bags.” “Those are presents too.” “Technically, yes.” “Focus. The presents are stacked beside the punch bowl. We grab the shiny boxes first.” “What if children chase us?” “I’ll throw candy.” “What if parents chase us?” “I’ll throw you.” “That’s not teamwork.” “It’s improvisation.” “What’s the escape route?” “Through the kitchen, out the back door, across the trampoline, over the hedge.” “Trampoline?” “Emergency exit.” “Party entertainers?” “Smile!” “Happy birthday! Please ignore the suspicious bulges in our costumes.” A child shouted. “They’re here!” They ducked. “Phase one begins now.” “Phase one is already terrifying.”
