Where There's a Will - A Village Library Mystery, #5

No good deed goes unpunished. The Whitby Library is a hive of activity. The basement of the old building is under construction and there are smaller projects on the main floor, too. The work is being done practically pro-bono by Cornelius, a Friends of the Library member who's a local real estate investor and builder and now a philanthropist. Then Cornelius is found dead in an elevator shaft under mysterious circumstances.
The focus falls on his family after his will is read and the amount of his fortune is realized.  Can Ann track down the killer before he strikes again? Where there's a will, there's a way.
