The quintessential hard boiled detective was the creation of Raymond Chandler. Despite being born in Nebraska, Chandler was educated at Dulwich College and was a civil servant before he started writing noir stories. When he had to choose a name for what would become his most famous creation, he opted for the name of one of the houses at Dulwich. I can’t be alone in finding that rather incongruous.
Philip Marlowe was named after a house at Dulwich College
