Sergeant Green

In the novel Cat Among the Pigeons, Sergeant Green is a Police officer in Hurst St Cyprian. He was on night duty and took the call from Meadowbank School for Girls to report that Miss Springer, the games mistress had been found murdered. Green immediately informed his superior Inspector Kelsey. Kelsey noted that "Death of a Games Mistress" sounded like a title of a thriller on a railway bookstall. Green agreed, remarking that the incident seemed "unnatural".
