The Psychotic Intruder

A mind on the edge of madness.

by Mike Bonath

For too long, thrillers have given us detectives in fancy offices and killers with elaborate schemes. Readers were starving for something grittier, something honest about the shadows lurking beneath everyday life. The Psychotic Intruder is the meal they have been craving

About Mike Bonath

Some people collect stamps. Others watch football on Sundays. Mike Bonath spent years wondering what it would take to push an ordinary person over the edge.

A British author with a taste for the uncomfortable truths we prefer to ignore, Bonath writes psychological thrillers that sit with you long after you’ve turned the last page. His stories don’t rely on car chases or far-fetched plot twists. Instead, they burrow into the quiet moments where a person decides to cross a line they can never uncross.

The Psychotic Intruder is his debut novel. It started as a question: what happens when a man who’s played by the rules his entire life realizes the rules were never playing fair with him? The answer turned into 81 chapters of mounting tension, moral compromise, and one unforgettable descent into darkness.

About the Book

Three powerful themes collide in this psychological thriller

Revenge

Johnny Allen never asked for much. A steady job. A wife who loved him. A life that made sense. But after years of swallowing small humiliations and watching others get away with things he never could, something inside him begins to curdle. Revenge isn't a plan. It's what happens when a decent man runs out of patience.

Madness

There's a moment in every spiral where you could still turn back. The trouble is, you never recognize it until it's behind you. Watch as the boundaries between right and wrong dissolve, one justification at a time. Madness doesn't arrive with warning signs. It creeps in wearing the face of reason.

Survival

When everything you've built starts crumbling, what are you willing to do to keep standing? Survival isn't pretty. It doesn't care about your principles or your reputation. It only asks one question: how far will you go?
