Lethal Fetish: A Riley the en ligne Exterminator Mystery by Lockwood, Jeffrey Alan NEUF

What is "normal" in San Francisco? In 1982, sexual experimentation was common. But naked corpses wearing flea collars?

Riley the exterminator is thrust into the kinky corners of a city where the boundary between normalcy and deviancy is blurred-where sex is handcuffed to violence.
This ex-cops journey begins at a deviants death scene, which leads to a rich kid who finds depraved delight in his six-legged playmates. Following a twisted track through sex shops and vile videos, Riley is soon over his head in terms of the human mind. He joins forces with a brilliant, beautiful psychologist to track a chain of blackmail and extortion into the depths of the human psyche, where degradation is an aphrodisiac.
As Riley questions social norms, he has no doubt that he must work closely with people he finds repulsive--but oddly principled--to infiltrate a secret cell devoted to a bizarre fetish involving insects, which has been driven underground by a holier-than-thou district attorney. The groups charismatic leader is taking them toward grisly murder to consummate their deviant desires.

A gruesome climax is coming, unless Riley and his trusted gang of misfits from Goat Hill Extermination
can achieve homicidus interruptus.
