The Purity Of Vengeance by Jussie Adler-Olsen

There's never any rest for Detective Carl Morck and his colleagues in Department Q.  There are always tons of cold cases to work and Morck just can't get the rest he knows he deserves.  His secretary, Rose, decides that the team's next case should be that of a brothel owner who disappeared without a trace twenty years ago.  As the team investigates, they find that there are others who vanished the same day and none of them have been heard from since.  What connection do they have with the head of a scary political party that is on the rise and whose politics are just this side of Hitler's?

Morck's right-hand man, Assad, seems especially upset about this case.  Morck is not sure what has struck a chord with Assad, but he knows that something has, and that something won't let him rest until the case is solved and the political head of party is stopped. 

In the meantime, Morck's life rolls on.  His ex-wife has agreed to a divorce, finally, but wants Morck to pay for her wedding to her new husband.  His stepson has left college just short of a degree and seems to do nothing but hang out.  His tenet has found a new lover, a physical therapist, who at least comes in handy in the care of Hardy, Morck's former partner who is now a quadriplegic and lives with him.  Then there is the delectable Mona, who Morck is determined to win for his mate. 

But the case won't wait on Morck's personal life.  It soon becomes clear that the team is being personally targeted by the culprits who think that if they eliminate Department Q that their crimes will continue to go unpunished.  Attempts are made on each member of the team and the chance of success rises with each try.  Can the Department Q team solve the crime before they lose their lives?

This is the fourth Department Q novel.  Jussie Adler-Olsen is Denmark's top crime novelist and he has gained many fans wherever his novels have been translated.  The characters on the team are each unique and their quirks merge satisfactorily to make them able to solve crimes that no one else has the time or patience to investigate.  This book is recommended for mystery lovers.
