The Investigation Discovery network says Lucci will host and narrate "Deadly Affairs." It said Thursday the new series will explore real-life cases of romance gone wrong and the crimes of passion that resulted.
Lucci won lasting fame as devious, often-wed Erica Kane on the daytime drama "All My Children," which aired from 1970 until ABC cancelled it last September.
Lucci describes "Deadly Affairs" as a "real-life soap." She calls her hosting role on the show "a perfect match."
She says she hopes the show will shed some light on human nature.
Filming of the 10-episode season is expected to begin in March. The premiere is slated for this fall.
