In June 2016, David Darlington, co-producer of Big Finish Production's Dark Shadows ranges, and I flew to New York to attend the Tarrytown celebrations for Dark Shadows' 50th Anniversary.

When the fans visited the Big Finish tables, they all had requests for what they'd like to hear from the range... "Something with Julia", "More Tony and Cassandra", "Quentin and Laura in Eygpt", "More Tony and Cassandra", "What Happened Next to Adam", "More Tony and Cassandra"... All weekend, over and over, we were asked for further adventures of Tony and Cassandra. And it wasn't just us... when we were chatting with Lara Parker and Jerry Lacy about the stories they had both recently been writing for Big Finish they told us they'd been delighted by the requests for more they had been getting.

...So make more Tony and Cassandra we did. David and fellow co-producer Joseph Lidster got to work on The Tony and Cassandra Mysteries and - with script-editor Alan Flanagan - assembled their team of writers and a company of actors who could take on the guest roles in all four plays. And over in LA Jerry and Lara got ready to crack four more cases, this time joined by Jerry's wife, the multi award-winning Julia Duffy, as Tony's secretary Rita Channing.

I attended the UK recording sessions and spoke to Davy, Joe and Alan... and the four writers and four guest actors to see what mysteries I could solve myself.
