The Psychotic Intruder

About Mike Bonath

Crafting psychological thrillers that explore the darkness within

The Writer

Mike Bonath is a British author whose fascination with human nature led him to write psychological thrillers that refuse to look away from uncomfortable truths. He didn’t come to writing through the typical routes. There was no MFA, no decade spent collecting rejection letters in his twenties. Life came first. The stories came later.

What draws Mike to psychological thriller isn’t the violence or the shock value. It’s the quiet moments before everything falls apart. The small decisions that seem harmless until they aren’t. The way ordinary people convince themselves that extraordinary actions are justified. These are the spaces where his stories live.

The Psychotic Intruder is his debut novel, and it’s exactly the kind of book he always wanted to read: grounded in real life, populated by people you might actually know, and unsettling in the way that lingers long after you’ve finished the last page.

The Process

Mike writes the way he thinks most compelling stories are built: from the inside out. He starts with a character and a question. For The Psychotic Intruder, that question was simple: what happens when a man who has spent his whole life playing by the rules finally decides the rules don’t apply to him anymore?

The answer became 81 chapters of mounting pressure, moral compromise, and the kind of tension that makes you forget you’re reading fiction. Mike believes the best thrillers feel inevitable, like you’re watching a car crash in slow motion and can’t look away. Every scene in this book earns its place.

He’s already deep into his second novel. If the first book explored what pushes someone to the edge, the next one asks what happens after they’ve already gone over.

Beyond Writing

Family is at the centre of everything for Mike. His daughter Lauren has been his biggest supporter from the beginning, encouraging him to keep going when the blank page felt impossible. He credits her with giving him the push he needed to actually finish what he started.

When he’s not writing, Mike can usually be found with a good thriller in hand or watching classic noir films. He has a particular soft spot for stories where the protagonist isn’t quite a hero and the ending doesn’t tie everything up in a neat bow. Real life doesn’t work that way, and neither do his books.

Mike lives in the UK and is currently working on his next psychological thriller.
