Dear Amy - Helen Callaghan

A local schoolgirl has been missing for weeks when Margot Lewis, agony aunt of the ‘Dear Amy’ advice column, receives a letter.

Dear Amy.

Ive been kidnapped by a strange man.

I don’t know where I am.

Please help me,

Bethan Avery

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?
