Danger by Design, by Helen Macie Osterman
In Danger by Design, senior citizen Net Petrone resides in a retirement complex. The previous owner of her apartment died of a heart attack, and to her son’s dismay, the woman’s will named a suspicious organization as heir. Her son is convinced there was a last minute change, and he is searching for that latest will.
Net learns a number of widows in the complex joined this society for the betterment of the environment, and that the founder, Brother Rupert, has convinced several of them to change their wills and leave everything to the society. Those who do soon die of “natural causes.” Net attends a meeting and realizes that the guests are served a drugged tea, and she rejects the pressure to join the society.
Net’s townhouse is broken into. She is convinced someone was looking for the will. She calls 9-1-1 and Rupert and his followers are caught and arrested.
