Killing begins with David paying a rare visit to his precocious step-daughter Elizabeth. Since Hilary’s death she has been living with her grandfather Harry and her Aunt but thinks it’s time she spend some time in London with David.
On the work front shady business Allan Hartman is back (last seen in Payment by Result) with a deal that would see David getting involved in a deal to import 10,000 tons of sugar into the country from Australia. David’s share of the profits would be a cool £50,000 but Main is sure there has to be a catch. Some smart investigative work from Walter uncovers a trail that indicates the sugar may actually be coming from Southern Rhodesia which was heavily sanctioned against at the time and trading with the country was illegal.
With Inge back in Norway Laura, who is also involved in the Hartman deal is back on the scene and keen to get her hooks into David. A surprise visit from Elizabeth shows a softer side to Laura too.
The second episode in a row to not feature Margaret and Henry. Obviously with David no longer a partner in the Leeds practice there is less need for them to be involved. Margaret Ashcroft who plays Margaret was also heavily involved in BBC series The Brothers at this time too.

classic quote
Laura: “how old is Elizabeth?”
