Things aren't always as they seem. `Deadly Affairs' drives that point home with true stories of romances gone terribly wrong. Whether it's a love triangle that violently collapses or a workplace affair that implodes, the re-enactments - two per episode - allow viewers to knock down closed bedroom doors, navigate secret trysts, and witness salacious liaisons. The stories contain first-person accounts from friends and family of the victims, and commentary from authorities and true-crime experts. Best yet? It's hosted by Emmy-winning actress Susan Lucci, who's been a part of a few steamy scandals and deadly dalliances in her daytime soap career.
