Gatekeeper

No. 14 in the Joe Gunther series. Epub version is an amature scan with errors, readable but frustrating.

Vermont detective Joe Gunther vows to stop the flow of drugs into his beloved state when in the course of a week a young heroin addict is gunned down while trying to rob a convenience store, a narcotics dealer is found hanging from a bridge, and the granddaughter of political bigwigs dies of an overdose.
