Walk the Line: A Serial Killer Crime Thriller

By Jack Probyn

On the dark web, nobody can hear you scream

Inside a London art gallery, a young couple are brutally murdered in a chilling tableau: their bodies dismembered, the word "liar" visibly inscribed on the woman's chest.

DC Jake Tanner, still suffering from the mental and physical toll of his last case, doesn't know what to think. Was this a revenge killing or something worse? His questions are answered when another body turns up and a series of alarming and gruesome clues begin to emerge.

This was the work of a sadistic serial killer, a monster hunting his victims online.

To stop the bloodshed and come face to face with evil, Jake must walk the line of duty and do everything he can to protect more innocent young women from dying.

But how do you catch a killer who hides behind a screen?


Walk The Line is a gritty crime thriller perfect for fans of Simon McCleave, Rachel Mclean, and the BBC's Line of Duty.
