The final case of the fourth series sees the idea of the evil that has been haunting the detective team in Whitechapel fixated on what was underneath the roads, the back alleyways and deep in the sewers. The sewers which take the waste out of the East End and in which a clan of cannibals have started to take the virtuous and honourable off the streets and like time, devouring them and leaving only the memory of them behind.
