Like The Haunting of Maddy Clare, this novel is set in England after WWI. Jillian Leigh gets notification that her eccentric uncle has died and she has to go to the village where he was working as a ghost hunter to go through his things.
Meanwhile, there's a ghost to catch and her uncle's murder to solve, and a handsome but unreliable Scotland Yard inspector to help out. St. James's novels are dark and melancholy and romantic and give a lovely feel of the time after WWI. And the ghost stories really are scary. All so good!
