Spoiler:

Gentleman detective Anthony Gethryn is in a race against time to save an innocent man from the hangman’s noose.

Colonel Anthony Gethryn is recalled from a holiday in Spain to solve a murder in the November fogs of London. He finds that his wife is sheltering Mrs Bronson, whose husband is in prison awaiting execution for the murder of a gamekeeper six months before. A petition for reprieve has been rejected and Bronson will shortly hang for someone else’s crime. Convinced by Mrs Bronson of her husband’s innocence, Gethryn embarks on a seemingly hopeless race against time to overthrow the guilty verdict and find the real murderer – and he has only five days before Bronson’s date with the hangman’s noose.

The Noose saw the return of Philip MacDonald’s gentleman detective Anthony Ruthven Gethryn, whose debut in The Rasp six years earlier had been a big success. Judged to be his best book yet, The Noose had the distinction of being chosen as the first book to be published in Collins’ Crime Club in May 1930, helping to immortalise it as one of the seminal books of the crime genre.
