Our History Influences & Inspires Us

"After a career as an entrepreneur and writer of nonfiction books, Marcia G. Rosen took on the pen name

M. Glenda Rosen to begin a career as a mystery author. The program delves into her experience of growing up with a father who was a gangster and the history of Jewish organized crime in America. Growing up with a father involved in organized crime inspired Rosen's fascination with crime and love for all things mysterious. Rosen's interest in crime was the catalyst for her creation of the book series The Senior Sleuths,

which features a criminal character modeled on her own father."

-Walter Ryce, Monterey County Weekly

When she was a young girl, Miranda Scott read dozens of mystery books by authors such as Agatha Christie and Raymond Chandler, and she loved characters like Sherlock Holmes. Then she began hearing their voices in her head, suggesting what she should and should not do. After a body is tossed into the lions’ habitat at the Zoo where she is the senior veterinarian, Miranda and Detective Bryan Anderson find themselves investigating several murders and dealing with a group of bad guys, while gangster friends of her father’s are trying to protect her. Plus, Miranda and Bryan alternate between flirting and fighting off romantic feelings. Murder seems to keep getting in their way!

“A delightful and charming new series filled with twists and turns, unexpected events and wonderful characters including several dead authors!”

Elizabeth Cooke, Author of 20 books.
