The Venom in the Valentine - Viola Roberts Cozy Mysteries, #5

Viola Roberts is down in the dumps after discovering her boyfriend, Lucas, is snowed in back east. Her best friend, Cheryl, agrees to substitute a girl's weekend for the romantic Valentine's Day he had planned. Massages and mani-pedis for the win! That is, until the hotel guests start receiving venomous Valentines, and one of them ends up dead. In a remote resort on the wild Oregon coast, it's up to Viola to get to the bottom of things before any more guests fall to the killer's poison pen. Viola Roberts Cozy Mysteries:1.
