The Angel Downstairs - Dechansay Bright Mysteries, #3

Some people never tell the truth. They daren't. Eric Dechansay is a successful artist with a popular studio in Paris, the life and soul of every party. Then the threatening letters start. Eric's past - and someone he thought was dead - have come back to haunt him. Hannah Dechansay knows nothing of her father's past but a phone call from her half-sister has her leaving Oxford and on a plane to Paris.
She won't be welcome. Eric's carefully constructed life is crashing around his ears and Hannah's determination to find out why will only make things worse. Her father's clearly frightened and he's lying. And then there's the piano player. Who is he anyway? As the stakes rise inexorably higher, who can Hannah trust? Each of the Dechansay Bright Mysteries is a standalone story.
