First off: I am not generally a thriller/suspense reader. I love it in movies and TV, but I have yet to find an amazing suspense author capable of keeping me fully-immersed in a crime story and it's characters. Though, I do plan to read the books by "Richard Castle" whether they are any good or not, just because I love him so much. I'm not sure what that says about me. 
 I watch quite a bit of crime TV and perhaps I have become way to accustomed to the fast pace at which the episodes progress. This book moved too slow for me, slower than I would have preferred. The characters were interesting but didn't blow me away. I will say that the ending caught me off guard and I thought it all came together very well, which says a lot. I definitely think that American mystery lovers would enjoy the change of culture offered by The Devotion of Suspect X. 
 If not for the ending, this would have been a 2 star. Mainly just because of the pacing. The fact is that this was just really not my thing. 
 I received this book free as an ARC from the Goodreads Firstreads program. Thanks!
