“Molly, explain again why we’re robbing a six-year-old’s birthday party.” “Because, Bill, six-year-olds have no concept of inventory control.” “They have parents.” “Distracted parents. Frosting-blind parents. Parents arguing with a magician named The Great Ploppo.” “I don’t like clowns.” “He’s a magician.” “He’s wearing enormous shoes.” “That’s misdirection, Bill. Respect the craft.” Bill crouched behind the hedge, clutching an empty laundry sack while balloons bobbed over the fence like cheerful witnesses. “So the plan is: we enter as entertainers?” “Correct. I’m Princess Sparklehoof, and you’re my loyal goblin accountant.” “Why am I always the accountant?” “Because you bring receipts to crimes.” “I brought one receipt. For grappling hooks.” “And tried to deduct it.” “That’s entrepreneurship.” “Focus. We sing, we bow, we locate the present table.” “And then?” “Smoke bomb.” “At a children’s party?” “It’s lavender scented.” “That makes it worse.” A shriek of laughter erupted from the yard. “Molly, what if they like us?” “They won’t.” “What if they invite us for cake?” “Refuse cake.” “I can’t refuse cake.” “You must.” “What flavor?” “Bill.” “If it’s chocolate, the mission changes.” The gate creaked open. A tiny pirate stared out. “Are you the pony princess?” Molly smiled. “Absolutely.” Bill sighed. “And I’m here about your taxes.”
