It is three years after World War I. Jo Manders is working as a paid companion to her husband’s aunt, Dottie Forsyth, after her husband Alex disappeared during the war. Jo has been in a limbo of grief and practical concerns. Although he is assumed dead, Alex has not been declared dead, so Jo cannot receive a pension. Penniless, she was forced to take the job with Dottie, who is often unpleasant or rude.
Jo has been traveling with Dottie through Europe buying art from newly impoverished nobility. But now they are on their way to Dottie’s home, Wych Elm House, which has been closed for some time. Dottie’s son Martin is returning home from a hospital where he’s been treated since the war, and Dottie has summoned home her husband with the plan of finding Martin a wife.
On the first day at the house, Jo walks into a room and sees a young girl in gray and pearls. It takes her some time to realize she’s seen a ghost—Dottie’s mentally ill daughter Franny who died during the war by falling off the roof. Franny had hallucinations and claimed that a demon dog named Princer protected her. In the village, Jo hears that children claimed to have met Franny and Princer in the woods. On the same day that Franny died, the body of a man was found in the woods, torn to pieces.
As Franny keeps appearing to Jo, sometimes leaving things for her to find, Jo begins to believe that Franny was murdered. She also wonders about one of Dottie’s clients, a mysterious Colonel Mabry, who seems to know something about Alex.
St. James just keeps getting better and better at her chosen combination of suspense, the supernatural, and romance. In this case, a little of the mystery was lessened because there was only one plausible romantic partner for Jo, but still, this is a very suspenseful, eerie novel.
