This eventful crime mystery is the 21th volume of the "DCI Ryan" series, but it has the same pattern as that done by the author with "The Shrine" and "Cuthbert's Way", by writing again a half mystery.
At the start of the book you'll find a phrase about Dan Jurgens's "The Death of Superman".
Storytelling is wonderful, but again this book is a first half of two books for the sequel will be "Poison Garden", the author should have made into one complete book in my opinion, for "Death Rocks itself hardly feature in this story, nevertheless the characters come splendidly to life in this tale about hidden decisions and killings, while the other scenery and history of Northumberland is greatly pictured and described.
The book starts off when the body of a talented photographer, William Harding, is found on the rocks beneath Dunstanburgh Castle, famously known as "Death Rocks".
This death is a hard nut to crack for there are hardly any clues concerning the perpetrator of this murder, and its not long before an innocent woman, Kath Hopkins, is found killed on a lonely road, and so for DCI Ryan and his team, with new addition DC Charlie Reed in their midst, to find the links between these deaths.
What is follow is an incomplete mystery with the mysterious "Circle" back again doing lethal mischief, with Gregson back in the limelight again while in prison, and although a couple of thugs are apprehended for certain deaths in this book, the master spider of the "Circle" still remains at large, although some connections are being made to break this web of evil and death, still unfinished business and thus sadly ending with a unnecessary cliff-hanger.
Recommended to all "DCI Ryan" fans, but for me this is only half a book of this up and down series, and that's why I like to call this episode: "A Half Finished Rock"!
