The story is based on the true story of the murder of Francis Rattenbury, and is faithful to the facts. However George's surname had to be changed as the real person (George Percy Stoner) was alive when the play was written and when the television adaptation was produced.
Final acting role of Harry Andrews (Francis Rattenbury).
David Suchet and Oliver Ford Davies appeared together subsequently in The Murder of Roger Ackroyd (2000) and The Way We Live Now (2001).
