No Room in Hell — William Schlichter

When the dead walk the earth, everyone has an agenda… St. Louis Detective Marcus Danziger seeks clues to his daughter's pre-apocalyptic murder by a serial killer. Excused from the case, Danziger returns to his precinct after the zombie outbreak with only one goal on his mind: to retrieve the evidence to destroy the killer before the entire city falls to the undead and the murderer escapes to the safety of Fort Leonard Wood. In a world where the rules no longer apply, Danziger won't allow the living or the dead to stop him.
