The Terrible People or the Gallows' Hand

A classic mystery novel and a cheeky sense of humour are often associated with the works of Conan Doyle, but Edgar Wallace's 'The Terrible People' is just as gripping and inventive as Sherlock Holmes. A gang of criminals return from the dead to haunt an heiress, as they seek to find redemption for crimes they didn't commit.
It is a novel which never ages and has remnants of a Gothic horror, as the protagonist attempts to exert revenge on those who have wronged him - his executors.
