Sensationalist taglines and blurbs

I finished reading Jane Casey's The Reckoning last night.  I enjoyed it and will publish a review early next week.  When I finished the book, I re-read the cover tagline and back cover blurb.  They've been written to give a certain impression of the book, but are really quite misleading.


Cover tagline: The police call it murder.  He calls it justice.
Back cover blurb:
To the public, he's a hero: a killer who targets convicted paedophiles.
 
Two men are dead already - tortured to death.
 
Even the police don't regard the cases as a priority. Most feel that two dead paedophiles is a step in the right direction.
 
But to DC Maeve Kerrigan, no one should be allowed to take the law into their own hands. Young and inexperienced, Kerrigan wants to believe that murder is murder no matter what the sins of the victim. Only, as the killer's violence begins to escalate, she is forced to confront exactly how far she's prepared to go to ensure justice is served...

He does not call it justice.  He's not a hero to the public; the public do not know about him because the police do not tell them.  In fact the public and media are entirely absent from the book.  The police do regard it as a priority and they throw more resources at the case, not less, as it escalates.  Kerrigan does not have to confront exactly how far she's prepared to go to ensure justice is served, she already knows and she never waivers from the task at hand.

Usually this kind of blurb writing, which bares a superficial resemblence to the story, wouldn't really bother me, but for some reason it tweaked a nerve very late last night.  Oh well.  The book's still worth a read.
