Fifteen minutes after Bill Griffith's father died from a bicycle accident in 1972, his mother turned to him and said, 'If I don't tell you this now, I'll never be able to tell you. I had a long and happy relationship with a man you knew slightly.'
Thus began Griffith's journey to reconstruct this hidden relationship between his mother and a deeply cultured jack-of-all-trades cartoonist and crime novelist. Griffith finally discovers the holy grail of his mother's past: her diary, an eloquent testament to her deepest feelings. Invisible Ink reveals the mother he never knew.
