Reluctance : Season 23 Episode 12

A student at Rod's school is reluctant to talk about who wounded him with a knife, but some dogged routine work by Reg and Diane searching through CCTV footage eventually gives the team a lead, linking the incident to the disappearance of a paroled prisoner last seen stealing bandages from a chemist's shop. The sight of Gina in her glad rags prompts June to wish for early retirement - and an early wedding. Gina and Smithy search for an absconded prisoner.
