However, one could make the panel idea a bit more broad-based by looking at fictional portrayals of Mary Shelley in general. Except I don't actually know of any beyond the aforementioned Doctor Who audios. So, help me, internets - have you read, watched, or listened to other fiction featuring Mary Shelley?
*I could propose a panel on "Audio drama as an under-appreciated art form in America." Do you think it would draw more audience members than panelists?
