[5] Capes was a prolific Victorian author, publishing more than forty volumes – romances, mysteries, poetry, history – together with many articles for the magazines of the day.
His early writing career was as a journalist, later becoming editor of the monthly magazine The Theatre, the most highly regarded British dramatic periodical of its time.
Capes wrote numerous ghost stories, which were later rediscovered by anthologist Hugh Lamb in the 1970s.
[9] Capes' Bembo: A Tale of Italy is a novel which takes place during the reign of Galeazzo Sforza, the fifteenth-century Duke of Milan.
The following year the Chicago Record ran the competition again, and this time Capes won it with The Lake of Wine, published by Heinemann.
