Gardiner cousins James and Susan, who haven't kept up with each other, are reunited at the reading of Uncle Sebastian's will: James gets the London townhouse, worth a packet, and Susan, a Swiss-trained restauranteur, is left the Blue Moon, a derelict inn in Essex. She patches it up, begins a romance with James, declines his offer to buy it, and soon has a smash-hit gourmet dining establishment on her hands--until someone poisons one of her customers, and then another, and business falters. Enter Chief Superintendent Henry Tibbett (Black Girl, White Girl, 1989, etc.) and his comfortably upholstered wife Emmy, plus sidekick Inspector Derek Reynolds, who chat up Susan's staff, a rival publican, and locals eager for a good chin-wag. Meanwhile, someone tinkers with Susan's car brakes, and she, perhaps rashly, marries James, then is almost drowned, while Henry and friends piece together a real- estate scheme and the dastards behind it. Echt cozy, and just the tonic for frazzled nerves: Moyes at her most companionable.
