A fascination with the occult is obviously what drives most of the Hammer output. This adaptation of the novel by Norah Lofts writing as Peter Curtis (and sitting accusingly on my bookshelf, for, oh, maybe 20 years at this point) by Nigel ‘Quatermass‘ Kneale, has a lot to recommend it. Not least is the leading actress, Joan Fontaine, in what would prove to be her last screen appearance, although there are those who swear Kay Walsh (once Mrs David Lean, the first of 4 in that role) is better. Anyhow, Fontaine is a schoolteacher who returns from a traumatising stint in Africa only to discover there’s a coven of the eponymous in a little English village where she has presumed upon a quiet life. There’s a fascinating supporting cast – Alec Cowen, Ingrid Boulting, Leonard Rossiter, Carmel McSharry, to name but some. Oh, that boy playing Ronnie is of course Martin Stephens, the little fiend from The Innocents. It was his final screen appearance – he went to Queen’s in Belfast and trained as an architect. A different time.
