This is quite an old interview, but the anecdote at the end is priceless.
It involves Jon Pertwee's wife, Bloody Marys, a fistful of valium and waking up in the shower fully clothed at 3am. I have a Sarah/Martha coda to The Shakespeare Code in the works (hmm, coda to a code? not sure that's grammatically correct), and the ficathon prompts will be sent out shortly.
