Gary's Cake (S04E06)

While Mrs. Burdett, adorned with jewels, dines at 'Pie in the Sky', a robbery unfolds, prompting DS Stringer to step in. His brusque approach puts off the entire restaurant crew, even the usually calm Henry. Stringer initially suspects Gary, then turns his attention to Nicola and her boyfriend Paul, accusing them of leaking details about the Burdetts' reservation to the criminals. However, it’s Henry’s thoughtful interrogation of the victim that uncovers the truth, allowing Gary to joyfully mark two years of sobriety.
