*US edition title: THE SIXTH IDEA*

Cold Kill is the seventh book in P.J. Tracy's bestselling Twin Cities series.

Two dead bodies.

On a cold winter's night in Minneapolis, two friends are brutally murdered on opposite sides of the city. It's clear to homicide detectives Gino and Magozzi that the men were targets - but why?

A decades-old conspiracy.

As Gino and Magozzi begin to uncover evidence, the clues rapidly start to disappear. Lost websites and missing CCTV footage lead them once more to Grace MacBride and her eccentric team of computer analysts - the only ones who can help.

A deadly attack that could bring a city to its knees.

But as more bodies appear, the team begin to realize that this isn't fresh blood - this is a case that stretches back sixty years. And something that has been lying dormant is now awakening.

As Gino and Magozzi race to find answers, they slowly uncover an unimaginable horror: one that they must stop if any of them are to get out alive . . .
