Aurora Teagarden Mysteries: Reunited and It Feels So Deadly (2020)

Ro, Sally and Arthur are attending their 20 year high school reunion held at a hotel in town. As with all high school reunions, there is a diverse mix of classmates: who want to retain their old high school glory; that used to date - many first loves - and that moved on to other life partners/spouses, which includes Ro with her first boyfriend, Parker Stevens, in attendance, and some who may want that first love rekindled; who surprisingly built friendships in the intervening time having not been friends in high school; and with a pending lawsuit of one against another thrown in for good measure. With all these behind the scenes issues, Ro, Nick and Arthur discover a dead body in the hotel pool during the reunion proceedings, the victim one of Ro and Arthur's former classmates who they discovered was murdered, specifically stabbed with a knife which is nowhere to be found. While Arthur leads the investigation for the Lawrenceton PD, Ro, Nick, Sally, Phillip, all at the proceedings, and their other Real Murders club members can't help but get involved, Ro and Sally who feel invested in the victim and suspects being people they've known all their lives, and Nick feeling invested in Parker being one of the suspects placing Ro at further risk in that connection to Parker.
