Although different from Dark Shadows, Edge of Night was an excellent show. As others have noted, its emphasis on crime drama and murder mysteries made it different from the other soaps airing at the time. Also, beloved, good characters were just as likely as the bad guys to be killed off, making its storylines suspenseful and unpredictable. Although, IMO, the show wasn't as good after the termination of long-time head writer Henry Slesar, it was still a sad day when this unique soap was cancelled.
By the way, between her stints on EON as Geraldine Whitney, Lois Kibbee appeared on the soap Somerset, where her son was portrayed by DS's Chris Pennock.
