The novel was to remain in print until Caine's death in 1931, when it was in its 29th English edition and had been translated nine times. The book was considered of such importance to Hall Caine's life work that the character of Mary O’Neill was one of the characters from his novels chosen to be carved onto his gravestone by Archibald Knox. For this character, Knox apparently modelled Mary's likeness on a photograph of Hall Caine's own wife, Mary Hall Caine.Norris, Samuel (1947), Two Men of Manxland: Hall Caine, Novelist; T.E.Brown, Poet, Douglas: Norris Modern Press, p.74
