It was slow paced for the first half of the book and then really gained momentum and I couldn’t put it down 

Gruesome but super engaging page-turner. This is a thriller that definitely lives up to the moniker. I felt as though I were reading a CSI episode or similar, and I mean that as a compliment to the author! She did a tremendous job walking us through the ins and outs of the investigation whilst maintaining a sense of mystery and tension. Olivier is a truly frightening villain, and Henley is a brilliant but archetypically flawed detective. It’s a match made in thriller heaven. 😅 Can’t wait to pick up the next book when it is released!

I particularly appreciated how thoroughly grounded this story is in its setting. I’ve never been to London, but having read the book I now know more about its neighbourhoods, traffic patterns, types of buildings and features of the Thames, etc. Because the descriptions of the setting are so realistic, I spent a lot of time searching the Google Maps street view to see some of the places mentioned. I recommend tearing your eyes away from the page periodically to do this, if you aren’t familiar with the city! 

great thriller, wish the sequel was out and I'll definitely be reading it when its released.
