A man is murdered. His son is suspected of the murder. Sherlock Holmes is invited by the young man's girlfriend to investigate into the crime. The case seems very simple until Sherlock suspects that the case might be more complicated.
Тайна Боскомской долины Set in 1888, Sherlock Holmes and Dr. Watson are called down to Boscombe Valley (a fictitious place in Herefordshire) to investigate the death of Mr. Charles McCarthy. Lestrade, a detective from Scotland Yard whose meagre abilities are often upstaged by Holmes's brilliant deductions, has concluded without much ado that it is a murder, and that McCarthy's son James is the killer. James was seen by one witness following his father to the nearby pond, and another, a young girl, saw the two remonstrating with each other by the pond.
