Between a rock and a hard place

According to the opening captions in Picnic at Hanging Rock (BBC2, Wednesday), ‘the infamous events’ it depicts ‘began whena mysterious widow purchased a mansion out in the Australian bush’. The first few scenes, set in the late 19th century, were then dedicated to proving quite how mysterious she was: Hester Appleyard (Natalie Dormer) wasn’t merely veiled, but also filmed largely from behind and — just to be on the safe side — in the dark.

What she might not be, though, is a widow. As she explored her new house, her voice-over dropped a series of dark hints that her mourning dress was a cunning disguise — and that she was in hiding from someone or other after doing somethingor other.

Either way, Mrs Appleyard soon turned the mansion into a girls’ school, which, if anything, allowed her to become even more camply sinister, as she donned some John Lennon specs and urged her charges to embrace purity and refinement.
