From The Jacket:
England, 1921. Three years after her husband, Alex, disappeared, shot down over Germany, Jo Manders still mourns his loss. Working as a paid companion to Alex's wealthy, condescending aunt, Dottie Forsyth, Jo travels to the family's estate in the Sussex countryside. But there is much she never knew about her husband's origins...and the revelation of a mysterious death in the Forsyths' past is just the beginning...

All is not well at Wych Elm House. Dottie's husband is distant, and her son was grievously injured in the war. Footsteps follow Jo down empty halls, and items in her bedroom are eerily rearranged. The locals say the family is cursed, and that a ghost in the woods has never rested. And when Jo discovers her husband's darkest secrets, she wonders if she ever really knew him. Isolated in a place of deception and grief, she must find the truth or lose herself forever.

And then a familiar stranger arrives at Wych Elm House...
