The previous J.S. Fletcher novel I read, The Three Days’ Terror, began as a straight-forward mystery novel but, by the end, had slowly morphed into a gothic horror. The Double Chance stays its course — it’s a simple murder mystery from the golden age of detective fiction. That said, it isn’t exactly a whodunit. There aren’t any clues to piece together in discovering what really happened, the wrongly accused man is never presented as anything but wrongly accused, and in all honesty, there’s no suspense whatsoever as the story unfolds.
Sir Robert Mannersley owns a coal mine that has made him quite a wealthy man. His daughter, Phillipa, is in love with her ne’er-do-well cousin, Clinton Mannersley. Clinton has been in prison these past three years for forging a check from Sir Robert but has recently escaped. He appears one night to plead his innocence to Sir Robert in person, but instead finds the great man murdered in his study.
It looks bad for Clinton, but Inspector Cortelyou, the famed Scotland Yard detective, believes another man committed both the current murder and the previous forgery. I don’t mind spoiling it (as Cortelyou certainly doesn’t): he thinks it’s Marshall Stead, chief cashier at the colliery. And… it is, but only after a fashion. Cortelyou was wrong in that Stead himself didn’t kill Sir Robert. A stranger did in a fit of madness. It was a lucky chance for Stead, who had been embezzling from his employer for years and was growing paranoid of being detected. In fact, it was a doubly lucky chance, as Stead was also angling for a way to steal the diamonds Sir Robert kept locked in his safe and this provided the perfect opportunity.
