Chloe has been meaning to check out the library ever since Louis had told her about it, despite the stick the librarian’s noticeboard message had implied was permanently lodged somewhere unspeakable, but she's only just now getting around to it.

She interrupts the little scientific monologue he's got going on with, “Hey, you got any newspapers?” before registering whatever is on the guy’s face and jumping about a foot straight into the air. “Christ! He could have warned me!”

The creepy mask had NOT come up in that entire conversation somehow!
