The Secret Casebook of Simon Feximal Books in Order

This book sits in KJ Charles's darker, more haunted corner. It is a Victorian occult romance told as a private memoir, with journalist Robert Caldwell looking back on his long partnership with ghost-hunter Simon Feximal. Right from the start, the frame matters. Robert is not just telling us about a case or two. He is telling the story of how a life was built, case by case, over twenty uneasy, intimate, dangerous years.

Simon is the kind of investigator who feels half legend and half terrible idea. He goes where something is wrong, whether that means a haunted house, a malicious spirit, or a stretch of folklore nobody sensible wants tested. Robert begins as an outsider, then becomes assistant, chronicler, witness, and eventually the person who knows Simon best. Their relationship is the real spine of the book. It grows slowly, under strain, and never gets separated from the work they do.

The ghosts are not the only danger.

What makes this story different from a straightforward paranormal romance is the format and the mood. It draws on the old occult-detective tradition, with case histories, creepy set pieces, and a sense that knowledge can be both shield and curse. But it is also deeply interested in secrecy, storytelling, and what it costs to live hidden from the world. Simon and Robert are dealing with supernatural threats, yes, but they are also dealing with loneliness, social risk, and the simple fact that love does not make a hostile society go away.

The setting does a lot of heavy lifting. Charles uses late Victorian and early 20th-century England as a place where science, spiritualism, journalism, folklore, and private scandal all rub against each other. That gives the book room for eerie houses, strange cults, brutal human villains, and moments when the supernatural feels almost ordinary because people have learned to carry on beside it. The horror can get genuinely unsettling, but the tone is never nihilistic.

If you are trying to work out what to expect, think ghost stories first, romance second, but with both parts fully developed. The cases are memorable, the atmosphere is thick, and the emotional arc lands because Robert's voice keeps everything grounded. It also connects neatly to the wider occult setting that includes Spectred Isle, but it stands perfectly well on its own. If you want KJ Charles at her creepiest, saddest, and most tender all at once, this is a very good place to be.
