Thomas Hanshew created the suave Hamilton Cleek: former criminal, lost heir to the throne of a small European country, and now private detective who consults with Scotland Yard. On top of that, he has the remarkable ability to change the features on his face, making him a brilliant undercover operative.
Hanshew died in 1914, but his wife, Mary, continued the series, and Cleek went on to track down thieves, murderers, and spies, with his friend Superintendent Narkom and his young assistant Dollops.
