Hayden's main works include And Then There Were None, The Moon and Sixpence, The Ape and the Information Discoverer, and The Magician's Handbook.
And Then There Were None was considered one of Hayden's most famous works. It was a novel about group adventures and horror stories. This novel tells the story of a group of strangers who encounter a series of horror events on a mysterious deserted island and how they eventually resolve these events.
The Moon and Sixpence was a novel about magic and mysticism, about a scholar named Hayden and his friends who explored the universe.
The Lost Ark (The Ape and the Poster) and The Magician's Handbook were about Hayden's coach and his students, and Hayden and his friends learning magic and adventure, respectively.

There could also be other interpretations, like Hayden being falsely accused of a 'cut throat' incident, adding more mystery and twists to the horror story.
