Jack Carter is a gritty, cold-blooded London mob enforcer directly lifted from the 1971 cult classic film Get Carter.
Unlike the more "fantastical" Victorian heroes of the earlier books, Carter is a stark representation of the cynical, violent underworld of the late 60s.
He enters the story on a singular, grim mission: to investigate the suspicious death of his brother in Newcastle.
While the League is busy dealing with occult conspiracies and psychedelic magic; Carter acts as a grounded, brutal force of nature
A man who doesn't care about "extraordinary" threats because he’s too busy ruthlessly dismantling the criminal syndicates in his path.
