When an 18p parking fine became a matter of principle, Brian Campbell realised his father's quiet defiance and dry humour had shaped far more than his outlook they'd built his life's foundation.
Told with warmth, wit, and a distinctly Northern Irish voice, The 18p Principle captures the remarkable life of Daniel Fleming Campbell a man of discipline, loyalty, laughter, and unwavering integrity. From jam-jar romances and postal protests to navigating the chaos of Derry through the Troubles, each story reveals lessons handed down from a father who led by example rather than words.
