Hammers On Bone by Cassandra Khaw

A grizzled private investigator prowls a rain-slick, neon-streaked city where missing persons cases bleed into cults and otherworldly horrors; when a routine job unravels, he must use his fists, his trusty hammer, and a hardboiled wit to confront grotesque, reality-warping forces. Told in a razor-sharp noir voice that mixes dry humor with visceral body-horror, the story follows his descent into increasingly surreal and violent mysteries as he wrestles with both monstrous antagonists and the scars of his own past.
