Clete 

Summary: Clete Purcel, private investigator, ex-member of the New Orleans Police Department, and war veteran with a hard shell and just a few soft spots, is Dave Robicheaux's longtime friend and partner in detective work. But he has a troubled past. When Clete leaves his car at the local car wash, only to return to find it ransacked by a group of thugs tied to the drug trade from Mexican cartels to Louisiana, it feels personal, his grandniece died of a fentanyl overdose, and his fists curl when he thinks of the dealers who sold it. Just as Clete starts to trail the culprits, Clara Bow, a woman with a dark past hires Clete as a detective to investigate her scheming, slippery ex-husband, and a string of brutal deaths all link back to a heavily tattooed man who seems to lurk around every corner. Clete is experiencing shockingly lifelike hallucinations and questioning Clara's ulterior motives when he and Dave start to hear rumors of a dangerous substance with potentially catastrophic effects. The thugs who destroyed his car might have been pawns in a scheme far darker than they could've imagined.
