Sir: What became of the three wonderful Quatermass series (The Quatermass Experiment, Quatermass II and Quatermass and the Pit) by Nigel Kneale? I still have the Penguin versions of the plays 40 years on. And my 10-year-old son would love to see Gerald Champion as Billy Bunter. I wonder (hopefully) what might be in the archives.
