Jane Darrowfield & the Madwoman Next Door by Barbara Ross - mmpbk

Mass Market Paperback.

Jane Darrowfield is using her retirement years to work as a professional busybody in her West Cambridge, Massachusetts community--but this time her client is a woman next door who thinks someone is following her... 

Megan, who's purchased the house next to Jane's, needs some help from her snooping neighbor. Megan's been having blackouts, hearing voices--and feeling like someone's following her. Are these symptoms of an illness--or signs that she's in danger?

Considering the extensive security system in Megan's house, it seems like she should be safe--yet she soon vanishes into thin air. Some think she's run away, but would this ambitious young lawyer on the partner track really miss a meeting with an important client? And where's Megan's cat?

The mystery is about to deepen when the cat is finally located in a hidden panic room--and as Jane and the police look into Megan's friends, family, and past, it may be time to sound the alarm...
