The Hollow Core — Lesley Horton

When housewife Diane Ingleby is shot dead in a car park, DI John Handford and DS Khalid Ali are called in to investigate. It's a baffling case - a kind considerate woman, gunned down in front of her husband and daughter. Handford has many questions - Was Diane the intended victim or was the killer after another family member? Was she as happy as she seemed? Why had she suddenly started keeping a diary? Is it shame, honour or old-fashioned fear that's keeping everyone quiet?
