The Cleaner by Mark Dawson

John Milton was the government’s most efficient assassin.

Until he refused to kill again.

Now hunted by the people who trained him, Milton is trying to stay out of the shadows for good — until a desperate single mother asks for his help. Her young son is being pulled into a violent gang, and Milton knows what happens to boys who don’t get out in time.

Stepping in means breaking every rule he once lived by. It also means drawing the attention of criminals, corrupt officials, and former colleagues — all determined to silence him.

As the pressure closes in, Milton is forced to confront a brutal truth: walking away was never going to be enough.

Perfect for fans of Lee Child, Orphan X, and no-nonsense action thrillers, The Cleaner is a gripping introduction to one of modern thriller fiction’s most compelling antiheroes.

The entire series is available now on Amazon and free to read with Kindle Unlimited.
