Arthur "Art" Shepard was a resident of Wisteria Lane.
Art was introduced by rescuing Lynette Scavo during a hostage situation in the supermarket. When Carloyn aimed to shoot Lynette and kill her, Art thew a can of soup at Carloyn's head, causing her aim to be off and only shoot Lynette in the shoulder. This act of heroism caused Lynette's son, Parker, to idolize Art. However, it's revealed that while Art pocesses good qualities, he's actually a pedophile. Lynette discovers this when she inadvertently ends up in his basement. The basement is full of toys and filled from floor to ceiling with polaroids of half-naked boys. Lynette then asked Karen McCluskey of advice and soon there were massive demonstrations outside the Shepherd’s house. After Rebecca died, Lynette came to rethink what she'd seen, and begged for Art’s forgiveness. He responded by saying that he had to hide his pedophilia from his sister, but now he was free of those restrictions. He then ominously stated that he was moving, and would be able to continue his sick ways. This suggested that he either was a pedophile or was pretending to sound like one as revenge for Lynette ruining his life and causing his sister's death.
