Impostors at Blue Heron Lake — Susan Page Davis

As Emily and Nate plan their wedding, they work to decipher their most baffling case yet. When Emily goes to interview Stella Lessard in her home, she finds the sweet older woman dead. Stella's odd will draws claimants to her estate. Nate, on the job as a sheriff's deputy, stops a young woman for speeding and is stymied. She has the same name as another young woman who is trying to claim Stella's estate. Who is the legal heir? The police rule Stella's death a homicide, and attitudes change. What is going on at Grand Cat Island? And who brought murder again to the sleepy town of Baxter? Emily lets her emotions get in the way as she tries to befriend the two girls. She winds up in danger that puts her ingenuity and her faith to the test.
