Gregg Wallace (Masterchef co-presenter, fond of a good wedding) sets out to solve a long-standing family mystery: what happened to his great-grandfather, Henry Roland Springett, who abandoned his wife and children, including Gregg's grandfather, and was thought to have deserted the Navy? Gregg turns detective and follows the clues that enable him to piece together Henry's life. Gregg uncovers a tale of infidelity, heartbreaking tragedy and cruel fate. The food expert is also given a formal portrait of his great-great-grandmother, but the tale of its origins and the fate of its sitter shocks the recipient.
