Case One (Part 1) (S04E01)

A celebration is underway for Buchan’s debut book, ‘A History of Murder in Whitechapel,’ and the team shows up to cheer him on. However, the night takes a turn when an elderly woman at the event makes some sharp remarks, particularly reminding Chandler of his lack of convictions, which dampens the mood. Meanwhile, Chandler and Miles are called to look into a strange murder case involving a vagrant who has been slowly crushed to death by falling stones.
