The Bradys and 3-4-6-9

A young cashier. A murdered uncle. And a number sequence that changes everything.

Dick Welch thinks he has problems. His uncle caught him with the girl he loves, two thugs jumped him in the park, and a mysterious detective slipped him a letter containing nothing but four cryptic numbers: 3-4-6-9.

Then he walks into the bank at midnight and finds his uncle shot dead on the floor.

Now Dick stands over the body—alone, holding a key no one knew he had—while a cold-eyed director and a suspiciously well-informed check clerk treat him less like a witness and more like a killer.

Dick knows the truth. He came here to do his uncle a favor. But the truth doesn't matter when every piece of evidence points at him, when two hundred thousand dollars in gold ingots have vanished from an unopened vault, and when the only man who knew the vault's secret spring is lying dead at his feet.

As the law closes in, Dick fights to clear his name before the real thieves disappear into Chicago's criminal underground. The famous Brady detectives are his only hope—but their agenda may not be as simple as it seems.

And those four numbers. They haunt him. Someone planted them on his person for a reason.

Can Dick unravel the Bank Burglars' League's deadly code before it buries him?
