The Twelfth Floor: an absolutely gripping crime thriller with a massive twist

DETECTIVE JACK MACINTOSH IS BACK - ON THE TRAIL OF A BRUTAL KILLER.

A punch in the face. A painful visit to the dentist. A summons from his boss. Detective Jack is having a very bad day.

It's then he gets the call. 'We've got ourselves a murder.'

Jack races to the crime scene: an empty flat on the twelfth floor of a rundown tower block. To be met with a truly shocking sight.

On the kitchen floor are two dismembered human legs. On the shabby sofa in the living room lie three severed arms.

In the bathroom, there's something even worse . . .

The following day, on a derelict industrial estate, two holdalls are found containing more human limbs.

Then an early morning passenger makes a horrifying discovery on the top deck of the Number 42 bus.

Someone is leaving body parts all over town. But who are the victims - and why have they been targeted? Jack and his team must piece together the parts of the puzzle before more people die.

Perfect for fans of Helen H. Durrant, Biba Pearce, Lynda La Plante, Angela Marsons and Rachel McLean.
