Not really a whole lot here. We have darker mentions of Jack "hunting," the first mention of the Openers/Closers thing, and the introduction of Needle and his as-of-yet seen on-page master, the Count. Hmmm, a bat named Needle, tied to a mysterious Count. Wonder where we could be going with this. At least Zelazny doesn't beat you over the head with the obvious.
In a similar vein, I like how he takes effective short-cuts to show us what some of these people are, rather than telling us. Such as "They had already been out. The broom beside the rear entrance was still warm."
