Mysterious Blood Relatives (Part III of Obscure Blood)

Detective Octa is supposed to hunt down criminals to face justice. Instead, he has embarked on a quest to take justice into his own hands by finding and killing his own brother, Juan. Ever since Juan murdered Octa's wife and disappeared, Octa has been in the grips of a deadly obsession with revenge.

As Octa hunts for Juan, mystery after mystery is revealed--but the more he discovers, the more violent and disturbed he becomes. When the stakes are this high, everything is personal, and Octa has every intention of getting away with murder.
