Mystery:

Picnic At Hanging Rock, 9.05pm, BBC2

We are very excited to see this reworking of Joan Lindsay’s 1967 mystery novel arrive on our screens tonight. It runs for six episodes and centres on mysterious widow Hester Appleyard (Natalie Dormer, above) as she purchases an isolated mansion out in the Australian bush with the plan of transforming it into a school for young ladies. Years later, though, the establishment is at the heart of a dark mystery.
