Everyone at Chantilly’s Bar noticed out-of-towner Camille Bayliss. Red lips, designer heels, sipping a Negroni. But that woman wasn’t Camille Bayliss. It was Aubrey Price.

Camille Bayliss appears to have the picture-perfect life; she’s married to hotshot lawyer Ben and is the daughter of a wealthy Louisiana family. Only nothing is as it seems: Camille believes Ben has been hiding dirty secrets for years, but she can’t find proof because he tracks her every move.

Aubrey Price has been haunted by the terrible night that changed her life a decade ago, and she’s convinced Benjamin Bayliss knows something about it. Living in a house full of criminals, Aubrey understands there’s more than one way to get to the truth—and she may have found the best way in.

Aubrey and Camille hatch a plan. It sounds simple: For twelve hours, Aubrey will take Camille’s place. Camille will spy on Ben, and the two women will get the answers they desperately seek.

Except the next morning, Ben is found murdered. Both women need an airtight alibi, but only one of them has it. And one false step is all it takes for everything to come undone.
