Actor Paterson Joseph’s debut novel, chronicling the life of the first Black man to vote in Britain, began life as a one-man play. It opens in 1775 with Charles Ignatius Sancho declaring his intent to revisit his diaries and set down his life for his son, Billy. Sancho is born and orphaned in 1729 on board a slave ship. On returning home, his master gifts the small boy to three maiden aunts in Greenwich, who treat him like a pet.
