The year was 1978. This novel shows that “drug use is NOT a ‘victim-less’ crime”.
Joe Kenda and Lee Wilson are homicide detectives with the Colorado Springs PD, but they get brought into the investigation of a string of overdoses from Mexican brown heroin laced with an unknown substance. (They will later discover it is fentanyl, an extremely powerful and easily lethal painkilling drug.)
The first three deaths are unrelated except for the method: an Airman from the USAF base, a ski instructor, and a well-known Native American activist for veterans of the Vietnam War. It was the beginning of a string of deaths that would involve a sociopathic genius junkie anestesiologist, his unwilling assistant, the Mexican cartel, local drug dealers, and lots of collateral damage.
It's an engaging read and a cautionary tale: know what your kids are doing, where they are going, with whom they're hanging out, and what they are doing. Don't teach your kids to lie by letting them get away with small ones; someday, Joe Kenda or someone like him will be asking them why they thought it would be fine to do something awful.
