Actually I think these audio dramas fit into DS continuity fairly well. Yes there are the occasional problems and contradictions, but these were evident on the show itself. It's hard to keep track of EVERYTHING that's established in 1225 episodes. The 8 full cast dramas take place a decade or so afte the series ended. I'm guessing, but that seems about right. They also take place before Return to Collinwood. The "dramatic readings are like puzzle pieces that fit in whereever the author wants them to. Some take place during Quentin's wanderings, one is set during the later life of Charles Delaware Tate, etc. In terms of the "Cassandra" and Tony one that's already been released (Death Mask), it concerns a chance encounter between Tony and "Cassandra". He happens to see her and remembers her. As I recall she was using the guise because being the former wife of Roger Collins could give her opportunities that other women could not have access to. There's no contradiction between the Rumson moniker she was using .She's like many shady people. She has many aliases she can use and picks the one that best fits the moment. I'm sure if she wanted to infiltrate a modeling studio, she'd go back to being "Mrs. Rumson". I think if you give them a listen, you'll see that they are a valid continuation of DS. In fact, with the exception of the new comic, they are the only licensing that's ever been a valid continuation of the original show. I'm lumping Return to Collinwood in with them because it serves as a sort of "backdoor pilot".
