The Other Mrs.

After relocating with their family from busy Chicago to a tiny Maine hamlet, Sadie and Will Foust discover their neighbor Morgan Baines dead in her house. Sadie, who is frightened by the idea of a criminal in her own backyard, is the one who is most upset by the murder on their little coastal island.

But Sadie's anxiety isn't solely related to Morgan's passing. Their haunting old house, with its run-down furnishings and spooky attic, was left to them by Will's sister when she passed away suddenly. It's Imogen, Will's unstable adolescent niece, who exudes a menacing and sinister aura. And the unsettling past is what keeps tearing their family apart.

Sadie finds herself enmeshed in the mystery surrounding Morgan's murder as suspicions are directed towards the new family residing in the town. Sadie has to exercise caution, however, as the more she learns about Mrs. Baines, the more she starts to understand how much she stands to lose should the truth ever come to light.
