When two men are killed in different parts of Minneapolis, detectives Gino and Magozzi soon discover that they knew each other and that their deaths appear to have been targeted attacks. With CCTV and other evidence mysteriously missing, they, again, have to rely upon Grace and the rest of her Monkeewrench team and their computing skills. As the body count rises, realisation sets in that this case dates back over sixty years – someone has to be stopped before even more lives are put in danger.

I’ve been a fan of the P. J. Tracy ‘Monkeewrench’ series since 2003 after reading the first book, Want to Play? It was with trepidation, however, that I read the latest instalment as I struggled with the previous novel Two Evils. Thankfully, Cold Kill (also known as The Sixth Idea in the US) is a return to form for the mother and daughter writing team.

The premise of the book is an interesting one, linking the production of the hydrogen bomb during World War Two to modern-day cyber attacks. Although there are lots of unrealistic elements to the book, it does pose interesting questions and makes you think about exactly what would happen if some sort of attack did destroy a country’s infrastructure.

Although this is the seventh book in the series, it is not essential to have read the previous six and it can be read as a standalone. Some back stories will be missed, however, such as the development of the relationship between Grace and Magozzi. The ending of Cold Kill was a huge surprise and would not have had the same effect if I had not read the other books.

An enjoyable and fast-paced read!
