Showing The English Daughter by Lindsay Townsend

Young widow Val Baker restores musical instruments, but fears her relationship with her Greek-Italian family on Corfu is broken beyond repair.

Returning to the island to work on a rare piano belonging to her Greek friend Alexia, she finds her dreams haunted by memories of Hilary; a young English girl raped and murdered ten years before. Val determines to uncover the truth about the case, and set to rest her own doubts about the involvement of her father, Yiannis, and half-brother, Markos, both policemen who were involved in the original investigation.

Joined by her friend Harry, Val begins to unravel the threads. When two strange tokens arrive, one for Alexia's daughter Chloe and one for Val, it becomes clear that Hilary's unknown killer is on Val's trail. Her search for the truth becomes a race for life.
