But when she and her 10-year-old son witness a man fall to his death, apparently by suicide, they are visited by the elderly Dr. John Watson and his charming, handsome son, Dr. John Watson Jr. Impressed by her forensic skills, they invite her to become the third member of their investigative team.

A gripping collection of 15 BBC Radio full-cast dramas written by Bert Coules, inspired by Sir Arthur Conan Doyle's original stories.
