Series 5 also demonstrates the variety that the programme could offer: in "Well—There Was This Girl, You See..." Marker again becomes involved in stolen jewels, but is exceptionally careful, too careful as it turns out, as his tactic of exerting pressure on a young man he thinks is involved backfires when he chooses to run to the police rather than Marker, and wrecks Marker's chances of getting a share of the reward money. An embarrassed Marker has to explain to an amused Firbank what has gone wrong.
