Oddly enough, the indicia states the first issue is "Anita Blake No. 11" and continues with this pattern up until #15 even though the cover title is "Anita Blake, The Laughing Corpse - Executioner" and the numbering on the covers ranges from 1-5, rather then 11-15.
This is one of several titles Marvel has put out in an ongoing translation of the Anita Blake novels into comic book form, chronologically they are as follows:
Original Prequel to the Novels
The First Death #1-2
Book One: Guilty Pleasures
Guilty Pleasures #1-12
Book Two: The Laughing Corpse
Book Three: Circus of the Damned
