In Book 4 of the MURDER IN MARIN series:
The death of Sausalito's retired fifth-grade teacher, elderly Henrietta Hammer, the town abuzz. But because she terrified her students--including Sheriff's Detective Eddie Austin, newspaper publisher Rob Timmons, and his assistant, Holly Cross--the news is greeted with bemused nostalgia.
But Hammer, who had been left a very wealthy widow by her enterprising late husband was the target of the town's charitable societies, none of which could afford to await her natural death. It appeared to be the perfect murder--until the secret that Henrieta kept for half a century inconveniently appears.
