A Certain Samaritan

A shoe found in Newcastle matches another found on a dead body found in a skip in Portsmouth. The victim had traces of heroin in his bloodstream, a wallet containing £300 and another man's credit card which seem at odds with his character. The investigation includes a possessive mother, a girlfriend, a homosexual beekeeper dying of leukemia, and a local drug dealer later found dead on a beach. Vera's private memories about her dead father are also stirred when Joe gives her an address for her father's mistress.
