Careless in Red (Inspector Lynley, #15)

Detective Superintendent Thomas Lynley retreated to Cornwall, hiking the coastline for a month. No matter how exhausting his days, painful memories do not diminish. Thomas discovers a young man who appears to have fallen. The closest town, better known for surfing than intrigue, seems an unlikely place for murder. Thomas is not a detective but a witness. The head of the vastly understaffed police department needs help with the mysterious woman whose cottage is near the discovery.
