The Echo Wife

Martine is a genetically cloned replica made from Evelyn Caldwell's award-winning research. She's patient and gentle and obedient. She's everything Evelyn swore she'd never be.

And she's having an affair with Evelyn's husband

Now, the cheating bastard is dead, and both Caldwell wives have a mess to clean up.

Good thing Evelyn Caldwell is used to getting her hands dirty.
