A bomb goes off behind Jimmy Quinn's speakeasy. He figures it has something to do with the books that arrived in the mail-ledgers filled with columns of cryptic handwritten letters and numbers. What about the smooth Nazi who says he wants to buy Jimmy's place? Why is a "moderately corrupt" police detective suddenly interested in "helping" Jimmy? Then there's the girl from Jimmy's past who just reappeared and has a hell of a story to tell.
There's also a missing $100,000. Numbers boss Jacob "the Wise" Weiss thinks that Jimmy has it. His enforcer, the fearsome Mercer Weeks, is keeping a close eye on Jimmy. And there's a dead guy in the warehouse, beaten to death and carrying a union card identifying him as Jimmy Quinn.
