The Black Arrow tells the story of Richard (Dick) Shelton during the Wars of the Roses: how he becomes a knight, rescues his lady Joanna Sedley, and obtains justice for the murder of his father, Sir Harry Shelton. Outlaws in Tunstall Forest organised by Ellis Duckworth, whose weapon and calling card is a black arrow, cause Dick to suspect that his guardian Sir Daniel Brackley and his retainers are responsible for his father's murder. Dick's suspicions are enough to turn Sir Daniel against him, so he has no recourse but to escape from Sir Daniel and join the outlaws of the Black Arrow against him. This struggle sweeps him up into the greater conflict surrounding them all.

It is both an historical adventure novel and a romance novel.
