Care home owner Penelope Pincott and hapless husband Owain enlist the services of Frank and Lu – someone’s trying to sabotage their care home but they just don’t know who, or why. Sebastian is sent in as an undercover care assistant where he encounters a mischievous ex-soldier who delights in the ensuing chaos. The investigation is flipped on its head when Penelope fatally plunges from the secluded flat roof. The only problem is everyone at the home has a cast-iron alibi for the time of death.
