Detective Chief Superintendent Tatton asks PC Bradley to harbour Barry Ross, who has turned queen's evidence at the trial against crime boss Michael James Duggan. To keep Duggan from finding Ross the whole matter is to be kept secret and Bradley cannot even tell his friends and colleagues. Not even his superiors. When Ross needs medical attention Jackie sends for Dr. Tricia Summerbee, whom she knows can be trusted. Greengrass has moved to the West Indies to live with his sister, who has won a lot of money and wants to share it with him. Bernie Scripps' stepbrother Vernon arrives in Aidensfield and moves in with David at Greengrass' cottage. Vernon is quite an entrepreneur and he has lots of ideas on how to improve Bernie's business.
