SIX WEEKS. SIX VICTIMS. NO CLUES.

A leading psychiatrist is found murdered by insulin injection in his home, with a note bearing a threat.

Detective Inspector Paolo Sterling and his team find themselves in a race against time to stop a killer from striking again - and again, five more times.

As the body count rises, Paolo and his team grapple with what could be their most complex case to date. But just when they think the game is up, they make a shocking discovery that leads them close to home.

With so much at stake, can DI Sterling uncover the truth before it's too late? Or will those closest to him pay the price?
