Aunt Dimity and the Family Tree by Nancy Atherton

If you haven't read the Aunt Dimity series, I highly recommend it.  Definitely start from the beginning. 
The series is set in a small English Cotswolds village named Finch.  A cozy setting with lovable villagers.  This is a mystery series and rather than a murder - there is a mystery to be solved.  There is always a lot going on to keep the pages turning.

The main character is Lori Shepherd, in this installment, her father-in-law, T. William Arthur Willis Sr., who's retired as head of the family Boston law firm, has relocated to Fairworth House, an old estate in Finch, to be near his grandchildren and son and daughter-in-law.

After much renovation, Lori helps her father-in-law to hire a live-in couple to cook and look after the grounds and to host a welcome party for the locals. When odd things begin to happen at Fairworth, including moving furniture and strange sounds, Lori turns to ghostly Aunt Dimity for assistance.
