Everyone in This Bank Is a Thief Hardcover – Ernest Cunningham Mystery Book 4 by Benjamin Stevenson

Everyone in This Bank Is a Thief by internationally bestselling author Benjamin Stevenson is the clever and wildly entertaining fourth installment in the Ernest Cunningham Mystery series. Combining locked-room mystery, murder, humor, and impossible crime elements, this twist-filled whodunit delivers another unforgettable case for amateur sleuth Ernest Cunningham.

A bank robbery is supposed to be simple.

Get in.

Get the money.

Get out.

But nothing is ever simple when Ernest Cunningham is involved.

While inside a bank during an attempted robbery, Ernest suddenly finds himself trapped along with a group of strangers. The doors are chained shut. No one can enter. No one can leave.

Then someone is murdered.

With the police locked outside and a killer trapped inside, every person in the bank immediately becomes a suspect.

The bank robber.

The manager.

The security guard.

The receptionist.

The priest.

The caregiver.

The patient.

The filmmaker.

The child.

And Ernest himself.

As secrets begin to emerge, Ernest discovers that more than one person arrived at the bank planning to steal something. Not every theft involves money, and not every criminal is who they claim to be.

With tension rising and danger closing in, Ernest must untangle a web of lies, hidden motives, and competing crimes before another victim falls.

Packed with sharp wit, ingenious clues, and unexpected twists, Everyone in This Bank Is a Thief is another brilliant mystery from one of the genre's most inventive voices.
