'Molly is an adaptation for the stage of the earliest of my television plays – Death of a Teddy Bear – which was written for BBC's Wednesday Play… The source of Death of a Teddy Bear was the Alna Rattenbury case, an account of which I came across in a paperback called (I think) Ten Famous Trials, left discarded in a railway compartment… I flicked through the pages of the paperback – it was stained and swollen as if a dog had urinated over it – in the cursory manner of one who has something of more consequence on the mind… When I arrived at Cambridge I left the book where I’d found it, but for the rest of that day, and for many subsequent days and (especially) nights, I was haunted by Mrs Rattenbury’s story – or what of it I could perceive behind the dozen pages or so in which her trial had been described. So when Kenith Trodd asked me if I'd like to try my hand at a full length television play the subject was already fully there, and at least partially shaped, even though unwritten. Which is perhaps why I didn't go back to Mrs Rattenbury herself, neither to her trial nor to reconstructions of the crime. I based my play on the effect that the dozen pages had had on me (the specifics being pretty well forgotten), changed the names and hoped that my sense of the drama would find its own form.
Molly was first presented in Britain at the Watford Palace Theatre in November 1977.
