Overdose: Death of a Punk Rocker

It seems everyone thinks rock-star Brad Stanley died of a heroin overdose. Everyone that is except for Brian. Don't let his guitar string salesman facade fool you. Brian used to play for the "B-movie Nightmares", but quit before they got big. Now the TV news says Brad OD'd, but Brian's going to find out what really happened. Was it a simple overdose or was there foul play? And if there was foul play, then who's to blame? A jaded drummer? A Korean Cowboy? A Satanic Ronald Reagan?! Brian asks "just one more thing" [ala Columbo] in his quest to seek out the truth. But no one said it'd be just another leisurely Sunday murder mystery. And it certainly won't be as polite.
