Michael Parker has only months left. The treatment options have been exhausted and it is now time to make peace with his past. There is just one final loose end, Dianne.

Dianne, an archaeology student, who broke his heart back in 1966 when she disappeared one day without a word. Dianne, who may or may not have been carrying his child.

Feeling he now needs closure he hires a firm of solicitors to track her down, wherever she may be.

James Lacey, reluctantly at first, takes The Letter from Michael Parker and picks up her trail in Ireland where he is given a series of blank postcards, hinting at where she could have worked over the years. With help from his girlfriend Jane, and best mate Jonathan, they dig deep into the past, trying to find this mysterious woman.

His quest takes him to France and as far away as India before returning closer to home to and the answers he seeks.

On his quest, James also finds out disturbing revelations concerning his own heritage in India.

This is the heartbreaking story of a love that should have been. The story of a letter and how jealously and deceit twisted two lives irrevocably apart. The story of one man's hope to make sense of a World where the saddest words are 'What Might Have Been'.
