Everyone wants a piece of millionaire Bennett Marshfield, owner of Marshfield Manor, and letters are coming in daily from those claiming to be poor relations. The elderly reclusive heir to the manor trusts no one but his aged curator, Abe. But when Abe is killed in a case of mistaken identity, things change dramatically.

Shaken by the murder, Grace Wheaton, lover of history and mystery, steps up to the challenge of assuming Abe’s responsibilities. But now some of the letters arriving for Bennett have taken a nasty turn, demanding millions - or else.

When an uninvited stalker shows up at the manor and then at Grace’s home, she and the groundskeeper, Jack Embers, join together to protect Bennett and Marshfield Manor - and get to the bottom of the strange events surrounding them. The pair must unravel a botched Ponzi scheme, some torrid Wheaton family secrets, and sour grapes out for revenge...
