The Case of the Llama Raising Librarian

After solving two murders in the "peaceful" town of Buttercup Bend, Cathy Carter needs a rest. She also needs time to consider the marriage proposals she received over the holidays. But when the town's librarian asks her to go undercover to solve the suspected murder of a co-worker who retired to a llama farm, Cathy leaves her kittens with her grandmother and her friends without an explanation.The only person at Oaks Landing Farm who knows the true reason Cathy and Mildred have come there is Danielle, the murder victim's daughter, who is having trouble convincing relatives and the police that her mother Doris was killed and didn't suffer the heart attack that was termed her cause of death.When it's proved that Danielle's suspicions are correct, the guests who attended the dinner at which Doris died are invited back for a reenactment of that night. These included the gardener, veterinarian, and farmhand who all had motives to murder Doris, as well as Doris' sister and her ex-husband. When the dinner is staged, the only clue Cathy receives is given by Danielle's grandmother who has dementia. Will this unreliable tip help Cathy deduce who murdered the llama raising librarian?
