Vincent O'Sullivan (1868-1940), born in New York to an Irish American family, moved as a child to London. As a young man, he soon became well recognised as the master of decadent and macabre fiction.

This collection presents five of O'Sullivan's creepiest tales:

- Will
- The Business of Madame Jahn
- A Study in Murder
- My Enemy and Myself
- When I was Dead
