O. Henry,
Makes the Whole World Kin
“ When a burglar is caught who does not wear a collar he is described as a degenerate of the lowest type, singularly vicious and depraved, and is suspected of being the desperate criminal who stole the handcuffs out of Patrolman Hennessy's pocket in 1878 and walked away to escape arrest.The other well-known type is the burglar who wears a collar. He is always referred to as a Raffles in real life. He is invariably a gentleman by daylight, breakfasting in a dress suit, and posing as a paperhanger, while after dark he plies his nefarious occupation of burglary. ”
