Would you risk your life to save a stranger?
Discover what happens next in the Sunday Times bestselling psychological thriller, Dear Amy . . .
A local schoolgirl has been missing for weeks when Margot Lewis, agony aunt of the 'Dear Amy' advice column, receives a letter:
I've been kidnapped by a strange man.
I don't know where I am.
Please help me,
This must be a hoax. Because Bethan Avery is another young girl, who went missing twenty years ago.
As more letters arrive, Margot becomes consumed by finding the sender and - unlike the police - convinced that the girls' disappearances are connected.
Solving this puzzle could save someone's life - but could it also cost Margot her own?
