This is the second in the Aiden Waits series.  Aiden is a police officer permanently working the night shift after a career shadowed in disgrace and turmoil.  In this book, we see flashes of Aiden’s childhood to understand more of why he is such a train wreck of a human being.  A man is found in a closed hotel under suspicious circumstances, as Aiden investigates he finds more questions than answers.  There is also a subplot of Aiden’s past that runs parallel to the main story line.  This was quite a fast paced and engaging read.   Fans of Jack Taylor would probably enjoy this.
