Books in the A Filton Shields Upi Mystery series

Strange forces are at work causing Penny Cornwall to see and hear people from the past and feel all their emotions. More disconcerting is the tune she does not recognise play over and over inside the English Cotswold stone cottage she shares with Harry Winchester. The music will not go away, spoiling the rural idyll she and Harry have found. And so begins a fruitless search to find the source of the music and its title, a quest that rapidly becomes an obsession taking over her life and threatening to destroy all that she holds dear. Can the intervention of eminent archaeologist Filton Shields, an Unexplained Phenomena Investigator, solve the music's connection to their cottage before it is too late and unravel the pieces of a tragic love story bound by the music transcending the barriers of space and time, thus proving walls really do have ears but sometimes they also have mouths with which to speak?
