Pie in the Sky (1994)

Season 4: Episode 6

An armed hold-up at 'Pie in the Sky' while jewel-rich Mrs. Burdett is present brings DS Stringer to investigate. His abrasive manner alienates all the restaurant staff, including the normally placid Henry. He accuses first Gary, then Nicola and her new boy friend Paul of passing on the information regarding the Burdetts' booking to the thieves. But Henry's judicious questioning of the victim brings the solution, in time for Gary to celebrate two years of sobriety.
