The Moonstone as pivitol urban Gothic literature?

I was just wondering what people's thoughts were on The Moonstone approached from an urban gothic stand point.
Admittedly it is no Dracula, Dorian Grey, of Jekyll and Hyde, but I think that in order to create the new genre of the detective novel, Collins plays a great deal on the Gothic narrative tradition, dealing with contemporary social anxieties surrounding addiction, wrongful incarseration and the psychology of crime.
Despite having such a strong basis in gothic traditions, is it going too far to say The Moonstone is actually a contributor to the urban gothic of the fin de siecle? Or is it right to recognise the influence of gothic and then go on to place it into another literary category?
Just a musing!
