It was inevitable that a person of so remarkable an appearance and bearing should form a frequent topic in such a village as Iping. (4.4)
Even before he's revealed as the Invisible Man, the stranger is so strange that he's a source of amazement. Amazement can lead to curiosity and, in this case, gossip. This is an example of people being amazed by relatively regular things – that is, compared to an invisible man, a strange visitor is small potatoes.

"There wasn't anything there!" said Cuss, his voice running up into a shriek at the "there." (4.27)
After Wells has spent some time showing us some amazement over relatively normal things, he hits us with this big shock: dude's invisible. Notice that Cuss's amazement starts to look a bit like hysteria at the end there, as he starts to shriek.
