You'd better cover your tracks

Detective Aiden Waits has seen better days.  When Sirens opens, he's been placed on suspension by the police force for trying to switch out drugs in the police evidence room.  As a disgraced cop, his superiors figure he would be the ideal person to go undercover in an attempt to find the missing daughter of an MP. 

Waits is fairly quickly able to trace the girl, Isabelle Rossiter, to the thriving drug den of kingpin Zain Carver.  It turns out that Zain employs attractive young women to pick up drug money for him.  Isabelle seems to be the latest addition to this group.  Poor Isabelle doesn't look like she's enjoying herself, though.  Why would she leave a seemingly comfortable upper-class home for the rough world of the drug trade?

While mingling in this dangerous world, Waits meets another female drug courier, Catherine.  He begins a relationship with her, but when a rival drug gang wants to take over Zain Carter's territory, Catherine becomes a pawn in their game.  As Aiden moves around in this shadowy underworld, he begins to suspect that some of the drug dealers he's interacting with might have something to do with the disappearance of a woman 10 years previously.  Aiden has to try to keep the two sides of his life separate while ensuring that neither he nor the people he's grown to care for wind up injured or dead. 

I found the story a little difficult to follow at times.  Aiden would be "called on the carpet" by either his police superior or a drug lord, and while speaking to them, he'd think, "I nearly told him everything," and I'd wonder, "About what???" The motives of everyone keep you guessing and you can never really trust what anyone says or does.  There is a second book out featuring Aiden Waits, so it will be interesting to follow up and see if he's been able to get his life back on the straight and narrow (although somehow I doubt it).
