Harry Manders (almost exclusively known as Bunny Manders) is a character in the popular series of Raffles novels by E.W. Hornung. He is the faithful companion of Raffles, a cricketer and gentleman thief, who makes a living robbing the rich in late Victorian British High Society.
Whereas Raffles is sharp-witted and cynical, the younger Bunny is more innocent and idealistic. Raffles often uses this naivete to his own benefit, and the two are commonly companions on the various burglaries they commit.
Raffles and Bunny had attended the same public school together, though there had been a considerable age gap between them. Bunny had always admired the older, charming Raffles who was a top sportsman and seemed to prevail in anything he did. After some years without contact, the two were reunited at Raffles' chambers for a baccarat game. Bunny returns later to ask for Raffles' help, as Bunny had fallen into considerable debt. Admiring his pluck, Raffles tricks Bunny into joining him on a burglary, and the two become companions in crime. Together the two launch a series of daring robberies on London society, until they are eventually exposed in The Gift of the Emperor and arrested on board a passenger liner. Raffles leaps overboard and is presumed drowned, while Bunny is returned to England to serve a term in prison. After his release some years later, a mysterious newspaper advertisement reunites him with Raffles and they both go undercover. The two men continue their crime spree, now acting as outlaws.
In 1899 both Raffles and Bunny volunteer for service in the Second Boer War where soldiers of the British Empire were fighting the Boer guerillas. After uncovering an enemy spy, Raffles is killed in battle and Bunny is badly wounded. He returns to England to write Raffles' memoirs.
