Unhinged by Sarah Graves
Jacobia Tiptree, or Jake to her friends, owns a big, old house that needs lots of repairs and fixing up. A onetime financial advisor to the Mob she now lives the peaceful life in Eastport, Maine. After falling from the roof many other accidents start happening to her friends and family. But it seems to start with the mysterious disappearence of Harriet Hollingworth, known asa busybody and not liked by anyone. While Jake and her best friend Ellie search for clues, a series of lethal mishaps occur. Ellie's son and husband are imperiled and a visitor to Eastport is killed. But why is all this happening and will they all survive.

Not the first in the series, I believe #7. I got rather annoyed how the answers seemed to just come and no one seemed very concerned for Jake's health as she managed to detour from the hospital several times. Perhaps since I haven't read the other books I don't have all of her quirks down. I might try to read the first book just to see if I can stand it.
