Showing Large Target by Lynne Murray

In Large Target, Josephine's second adventure, she travels to San Diego to deal with a world-class dysfunctional family and a murder with military attitude:

"A woman of my size is supposed to be invisible -- a factor that often proves useful in my line of work. My very existence bothers some people to the point where they erase me from the landscape. They look, and turn away. So I do my job, go home, take off the please-ignore-me black polyester pantsuit, and put on my preferred red silk lounging pajamas."

Jo's eccentric billionaire employer gives her an assignment that's personal, although she won't say how. Things go off track immediately when Jo encounters a slain defense contractor, a kidnapped admiral whose family may not want him back.
