What's saying this paragrapg. I hardly have a clue:
January was the coldest month, and more than once the nightwalkers slipped on patches of ice criss-crossing the rutted streets
Main problem is at "slipped on patches of ice criss-crossing the rutted streets."
Is this saying night prowlers slip over iced fragments all along the streets which have a lot of holes?
A rut isn't exactly a hole - it's more of a groove. If the streets are dirt and there are carriages, the wheels will make ruts. These might easily fill with water, and when it freezes, you will have lines of ice all over the street.
But you have the basic idea, yes.
