Murders most matronly: A Leela/Meena Mystery (Volume 1)

Cousins Leela and Meena Rao, widows of twin brothers, lead quiet retired lives in Tucson, Arizona, until a serial killer descends on their South-Asian community, targeting elderly women. Leela is a retired professor of behavioral clinical psychology from the University of Arizona, and Meena a retired corporate lawyer. They persuade Deputy Chief of Police Murali Kalluri to let them assist him in catching the killer. Their sleuthing instincts turn out to be invaluable. As the killer's behavior escalates, however, Kalluri realizes that his two assistants fit the profile of the victims.
