The Disappearance of Douglas White

Sally Nimitz is in the middle of a family crisis when a local police detective turns up at her front door. David White and Sally are not strangers. She was the delivery nurse when his wife had a baby, and he was in charge of the investigation of the murder of Sally's neighbor, Amelia Marsh. Now Detective White has a personal request. Would Sally use the observation and deduction skills she displayed before to help find his missing brother? Has Douglas White, a successful and respected widower, deliberately disappeared?
Her friendsâ€"and fellow amateur sleuthsâ€"George Thomas and Anne Carey, are only too happy to once again give her a hand and soon, they find themselves far from home in a very precarious situation.
