There are so many working parts to this story that I had a hard time keeping track of everything.  I generally enjoy stories with POV changes each chapter, but this one definitely challenged me.  The book was translated from Spanish to English.  It’s set in Spain.  Characters include an inspector, a super genius, local police, and the Russian Mafia!  I didn’t feel like the character development was significant.  They were difficult to for me to like.  I also had a difficult time following the narrator.  I found myself being distracted by pronunciation.  All the characters sounded exactly the same unless it was a Russian because of the accent.  It was slow-paced.  There was so much build up.  I kept waiting for the ball to drop but it kept dragging on.  When the twists finally started happening they were great! I think this one just missed the mark for me.  Overall it’s a good story; perfect for readers that like the Russian Mafia and tons of back story!
