Theories that thrill. Realities that kill. A ticking clock.

When an esteemed criminology professor is found lifeless at an international conference, it's up to DCI Whitney Walker and forensic psychologist Dr Georgina Cavendish to unravel the mystery.

The professor had unveiled 'Death's Shadow' - a ground-breaking but unsettling theory that could redefine the understanding of serial killers. The theory captivated and unnerved scholars, leaving a lingering air of dread within the conference halls.

When another delegate meets a gruesome end, it becomes horrifyingly clear: the conference has become a hunting ground. Is Death's Shadow serving as a blueprint for a real-life killer, or has the professor's intellectual arrogance unwittingly unleashed a monster?

Time is running out. As the conference draws to a close, Cavendish and Walker must decode a mind warped by twisted logic. Lives hang in the balance - can they crack the case before Death's Shadow strikes again?

For fans of Rachel Abbott, Angela Marsons and M.A. Comley, Death's Shadow is the thirteenth book in the Cavendish & Walker crime fiction series.
