Set in London in 1304, Hugh Corbett is engaged by the King to investigate two murders which occur shortly after the fall from power of Walter Evesham, Chief Justice. Evesham himself is soon found slain, and it seems a ghostly assassin is on the hunt with Corbett close behind.
The Mysterium is the name of an assassin who stalked London long ago and many believe he has returned; or is this the work of a new killer?
Doherty is an expert in transporting the reader to medieval London; I was able to experience the smells, sights and sounds as if I was almost there. I definitely felt cold reading this novel too, it seems every character was cold at some point.
This was another great stand alone medieval mystery with Corbett revealing his findings at the end in ordered and thorough detail. Very satisfying for the reader who enjoys finding every loose end tied up. I'd recommend this book to any historical fiction fans, and fans of the crime genre who don't mind going back in time a few hundred years.
My rating = ***
