Detective Comics#112(1946)

Batman and Robin tour the Batcave's Trophy Room and reflect on one particular trophy, a single $1 bill from a "crime that never happened". Bruce Wayne picks up a masquerade costume at Papa Brugel's Costume Shop. Soon after, August the bookkeeper realises that they're missing $99 from the cash register. The close-knit group of four employees begin to suspect one another. At the charity masquerade ball later, Corinne the seamstress dresses as Catwoman and pulls off a daring stunt in an attempt to win the $100 costume prize. When confronted by Batman later, she says she thinks Eddie the fitter took the money, but that he must’ve had a good reason. The following morning, Batman and Robin tail Eddie to a carnival, where he’s about to wrestle a strongman to win a $100 prize. Batman stops him before he does, with Eddie claiming he thinks Corinne took the money. Batman disguises himself as Eddie and wins the $100 for him. Later that night, Papa Brugel goes to sneak $100 into the register so that nobody will get in trouble. Mistaking him for a robber, he tackles August as he too tries to replace the $100. With all the suspects cleared, Batman is at a loss for how to solve this mystery. It’s only the following morning that he realises what happened. He returns to the shop as Bruce Wayne, as Corinne hadn’t been paying attention when she'd given him change for his costume and accidentally gave him a $100 bill instead of a $1 bill.
