This Body of Death / Elizabeth George

DI inspector Lynley returns to New Scotland Yard as an advisor to the new acting superintendent, Isabelle Ardery, as she struggles to prove her worth in solving a puzzling murder. The usual cast of characters at the Yard play off each other and try not to read too much into Lynley's return. The mystery stretches across London and down to Hampshire and back, and ties in to an old crime, the story of which is artfully interwoven with the modern crime. 692 p.
