Inspector Sullivan is played by Tom Chambers. He arrives in Series 2 as the police inspector taking over from Valentine. The early stories present a confident officer who expects an orderly investigation and has little patience for Brown’s unofficial involvement. That friction gives way to a more layered professional respect as Sullivan encounters the priest’s ability to understand motive and personal history. The changing relationship is a long-running part of the programme’s police-parish dynamic.
Sullivan’s story moves through distinct phases: his regular run in Series 2–3, guest returns in Series 7 and 8, then a return as the lead inspector in Series 10–13. That later position gives the character new authority and a broader relationship with Brown; the priest is no longer simply the unofficial helper who irritates a newcomer. Sullivan’s connection with Mrs Devine adds a personal strand to the recent stories, while his long experience with Goodfellow grounds the police work in the same village relationships that Brown knows. Tom Chambers is named here for the role of Sullivan in Father Brown, with no personal biography.
