He is quite brutish and seems to enjoy nothing more than killing and destroying things (even practising his golf swing with live toads). He does not speak much, and when he does, his statements are often laconic and blunt. Vandemar ( Clive Russell) – Dull-witted, tall, and gangly, Vandemar is Croup's polar opposite.

Much of the imagery used to describe him is that of a fox. He is the brains of the pair and seems to be the one calling the shots, and he apparently has a taste (literally) for fine china. Vandemar, he seems to be able to simply move from one place to another very quickly despite his ungainly appearance. He is short, fat, and speaks in a pompous and verbose manner.

Croup ( Hywel Bennett) – The talkative half of the pair of assassins, the Messrs. She possesses her family's innate ability to 'open' things (and not just doors).

Door ( Laura Fraser) – A young woman from London Below, the daughter of a noble family who were all murdered shortly before the beginning of the story.

London Below is a parallel world in and beneath the sewers. In London Below the various familiar names of London all take on a new significance: for example Knightsbridge becomes 'Night's Bridge', a stone bridge whose darkness takes its toll in human life The Angel, Islington is an actual angel. He loses his flat, his job, and nearly his mind as he travels London Below in an attempt to make sense out of it all, find a way back, and help Door survive as she is hunted down by hired assassins. Despite his fiancée's protests he decides to help her upon doing so he ceases to exist on Earth and becomes real only to the denizens of 'London Below', whose inhabitants are generally invisible and non-existent to the people of 'London Above'.
