The Man in the Brown Suit (Audio cassette)

On the platform of a London Tube Station Anne Beddingfeld watches in horror as a man looks in her direction, panics, falls on to the tracks and is killed. But who is the mysterious man in the brown suit who comes forward claiming to be a doctor? And what connection does he have to the scrap of paper with a name and date on it that Anne finds at the scene? This puzzle takes Anne to South Africa in the company of some characters she would have been better off never tangling with.
