The series was later shown in the United States in 2006 and 2007 under the title Jericho of Scotland Yard as part of the PBS Mystery!

Detective Inspector Michael Jericho is the son of an English policeman who returned from World War I a violent and changed man.

Young Jericho witnessed his father shot and killed in his own front hall by two gunmen.

He has a faithful secretary, a tough sergeant, a younger DI assistant, and, as comic relief, an informer who is a street fence.

"A Pair of Ragged Claws" is quoted from a book of Eliot poetry owned by the mistress of a murder victim in that episode.
