Molly adjusted her fake mustache in the mirror of their van. "So we're really doing this? Breaking into a six-year-old's birthday party?" "The presents alone are worth thirty grand," Bill said, checking his clipboard. "Thirty grand of unopened merchandise, Molly. It's perfect." "It's insane. We've robbed banks." "Exactly. We're overqualified." Bill pulled out the floor plan he'd drawn from Google Earth. "I'll go in through the kitchen door. You create a distraction." "What kind of distraction?" Molly asked. "Tell them you're a character actress. Start doing Shakespeare in the living room. They'll be confused enough that nobody sees me loading the van." "Shakespeare? Really?" Molly groaned. "You got a better idea?" She didn't. The two of them had stolen from the Metropolitan Museum and dodged Interpol in three countries, but somehow this felt like their lowest point yet. Still, bills didn't pay themselves. "Fine," Molly said, straightening her costume. "But I'm not doing Hamlet again." "Macbeth?" "Deal." They climbed out of the van and walked toward the house, two highly trained criminals about to commit their most ridiculous heist ever.
