This book is Book 3 of the New Scotland Yard mystery series.
Acton and Doyle are married detectives, working at New Scotland Yard. They are as different as night and day, but their passion for their work and each other binds them together. When a string of murders occurs, it looks like someone is going back and murdering people who they deem have gotten off lightly. Doyle tries to work under the radar, but is shadowed by a stranger. The danger builds and the plot twists and turns until its conclusion.
I enjoyed this fast-paced mystery which I got from Net Galley. I have to say, though, that I think I would have benefitted from reading the prior books in the series. It stands alone, but I can see that I missed some important events and character development.
If you like mysteries, especially my favorite type: the British variety, then you should check out this series!
Thanks, Net Galley and Kensington Books, for my copy!
