At the reading of Mrs Llewellyn-Smythe's Will, one of the shots of those present is clearly mirrored. This appears in a brief wide view of four of the characters sitting in the reverse order from the order in which they appear in the rest of the scene.
This episode is based on Agatha Christie's book Hallowe'en Party (1969).
