Sophie "Phee" Kimball wants to get some work done at her private investigation company in Arizonaand she's distracted already by her old crush, who's arriving from Minnesota to join the staff. The last thing she needs is constant updates from her mom on the local production of Agatha Christie's "The Mousetrap." Practically everyone from Mom's book club and retirement community, with the possible exception of her chiweenie, Streetman, wants to join the cast and crew. But someone's playing the role of the killer for real. After a much-despised cast member is found dead on a catwalk in the theater, Phee has no choice but to be drawn into all the backstabbing and backstage gossip. Especially if her drama-queen mother is right about the vaguely threatening note left on her windshield, which could mean curtains for another victim.
