Tina Craig longs to escape her violent husband. She works all the hours God sends to save up enough money to leave him, also volunteering in a charity shop to avoid her unhappy home.

Whilst going through the pockets of a second-hand suit, she comes across an old letter, the envelope firmly sealed and unfranked. Tina opens the letter and reads it - a decision that will alter the course of her life for ever... Billy Stirling knows he has been a fool, but hopes he can put things right. On 4th September 1939 he sits down to write the letter he hopes will change his future. It does - in more ways than he can ever imagine...

The Letter tells the story of two women, born decades apart, whose paths are destined to cross and how one woman's devastation leads to the other's salvation.
