Having taken on the Sherlock Holmes role, Anne recruits her Watson in the person of wealthy socialite Suzanne Blair. The ladies put their heads together and make an astonishing discovery. They also make plans to continue their sleuthing once they arrive in Cape Town. Provided, of course, that Anne survives the voyage… "Attack by Night" is the fifth episode of a multi-part adaptation of Agatha Christie’s The Man in the Brown Suit.
