Colonel Barker (French: Colonel Ronchont) is a retired Army Colonel who lives at 21 London Road, and as such is a neighbor of Jacob Balthazar, the murdered artist. It was he who leads the residents up into Balthazar's room when his parrot Polly returned there after escaping from Tintin's apartment.
