 Frank Milner has recently lost his grandchild Claire and blames Nick Rowan for her death. He goes to Aidensfield to get back at Rowan by making him lose somebody he loves. Sergeant Blaketon spots another chance to get Greengrass behind bars when the old scoundrel is spotted trying to get into captain Braithwaite s barn. But Greengrass has been asked to clear out the barn and when he an Rowan take a look around they discover the pieces of an old car. Greengrass thinks he has made the deal of his lifetime when he sells the pieces to Rowan for £25, but is not quite as happy when he learns the true value of the wreck.
