Crop circles often appear in Wiltshire but this one on Hackpen Hill is a bit different: the patterns seem to be trying to convey a message and the dead body in the middle is certainly not a common feature. DI Silas Hart is at a loss until he happens upon Jim, a Porton Down scientist who is convinced he is being pursued by MI5 for wanting to tell the truth about what is happening at the government laboratory. With Bella, a trainee journalist intent on telling Jim’s story, someone is desperate to stop the truth being told and is prepared to kill to achieve their aim.

This is an intense read that grabs you right from the very beginning and keeps you hooked until the last page. There is a lot going on with elements of mystery, thriller and police procedural but the short pacy chapters keep you gripped, making you want to read ‘just one more’ before putting it down. It is really well-researched and I do not claim to understand all of the science, but this did not hamper my understanding or enjoyment of the plot in any way.

There are two sets of main characters, each with a distinctive role in the plot. In Jim and Bella, we have like-minded people who have been thrown together by an unknown person, each of them reliant upon the other. I genuinely feared for Jim’s safety throughout the book as it becomes apparent that he seems to have information on what message the crop circles are trying to convey. Likewise, as Bella became more and more embroiled in Jim’s world, her well-being became more of a concern, especially as other aspects of her life start to become more worrying. I admired the courage of Jim and Bella; Jim in particular was a favourite character.

I loved the relationship between the two main police characters and enjoyed how the focus was very much on their part in the investigation and not on their private lives. I feel that there is scope for DI Hart and DC Strover to appear in another book so I hope it’s not the last we see of them.

I thoroughly enjoyed the intelligent plot of The Man on Hackpen Hill and found myself drawn into the plot, desperate to see if my theories were correct! A great read.
