Inspector Mallory, played by Jack Deam, joins the series in Series 4 and remains the principal inspector through Series 9. He is impatient with Father Brown’s interference and often wants to close a case on the evidence immediately in front of him. The recurring disagreement is comic, but Mallory is more than a caricature of police stubbornness. His work, family attachments and loyalty to Sergeant Goodfellow reveal a character with strong feelings beneath the sharp manner.
Mallory and Brown develop a familiar pattern of friction, followed by reluctant cooperation when the priest sees an angle worth hearing. The balance gives the middle years a distinctive police-parish rhythm. His professional relationship with Goodfellow adds a second layer: Mallory can be demanding, while the sergeant’s steadier judgement often grounds their work. Mallory’s last listed episode is The Red Death, the Series 9 finale. That story gives his run a clear stopping point while the series later brings other inspectors back into Brown’s world. Across the middle years, his blunt exchanges with Brown become part of the case rhythm, while Goodfellow’s steadier manner reveals Mallory’s protective side. The two-part finale places his last appearance beside returning figures from earlier police eras.
