Man In The Microwave Oven, Susan Cox

Six months after the events of Man on the Washing Machine, Theo Bogart is doing the long-distance relationship thing with Ben and settling into her San Francisco community; so it's a shock  when a blackmailer threatens to expose her true identity and promptly meets a sticky end.

 Theo and the other residents become suspects and days later a mysterious foreigner shows up at Theo’s shop looking for her Grandfather, causing all manner of family secrets to come tumbling out of the closet along with another body.

 With those she loves now at risk, Theo is determined to find a connection between the victims. Is it espionage, embezzlement, love, real estate, wine, wimples? And could this put her in the killer’s sights?
