Haley Blue, the singer in Castle's daughter's favorite band The Blue Pills, is found in an alley with a broken neck, murder staged as suicide, before she can break up the band. Stalking fan Franco Marquez, against whom she got a restraining order, says he overheard ex-con guitarist Zack Metzger threaten her. Both Castles add lyrics analysis to confusing facts about a possible band reunion and drug (rehab) history involving her sister Skye, producers couple Ian and Bree Busch and ex-producer John McGinnis.
