Next week Investigation Discovery invites you to spend your afternoons with Josh and Reva Shayne (“Guiding Light”), or at least with their portrayers Robert Newman and Kim Zimmer, as the network launches “Days of our Knives,” a programming initiative aimed at Women 25-54.

Investigation Discovery, which recently announced its plans to integrate several daytime stars into various aspects of its daytime programming block in the coming weeks, has released the first promos and trailers of “Deadly Affairs,” the new series about love triangles gone wrong and marriages that end in murder hosted by “All My Children” vixen Susan Lucci (ex-Erica Kane).
