by Frances Iles
The last of four parts dramatised by Philip Mackie
Starring Hywel Bennett as Dr Bickleigh
with Thorley Walters as Sir Francis Lee-Bannerton, Michael Aldridge as Sir Bernard Deverell and Cheryl Campbell as Madeleine

Though Dr Bickleigh has been arrested for the murder of Julia, the main evidence against him is his attempted poisoning of Madeleine and Chatford. Everything hinges on the potted meat sandwiches.
