If you probe deep enough, it seems that almost every mystery and murder in Salem can be connected to André DiMera. While being a plague on the residents of Salem, André usually pins all of the blame on his identical cousin, Tony DiMera (both characters played by Thaao Penghlis, who also appeared in daytime’s Santa Barbara and General Hospital).
André first appeared on Days of Our Lives in 1983, when Stefano summoned him to Salem to undergo plastic surgery and replace his son, Tony, and be the perfect evil henchman. For over 20 years, André masqueraded as Tony and orchestrated some of the most memorable storylines, including the Salem Stalker, Aremid, the Salem Strangler, Melaswen, and a major part of the Brady-DiMera Feud.
