The interlude 2 chapter is the one Marguerite Olsen (Shadow's neighbour in Lakeside) calls her sister Sam and tells her that Alison McGovern has gone missing last week and that she's got a new neighbour.

However, I don't get why she says it's been only a week since Alison's disappearece because on chapter twelve, the one Shadow meets with goes "behind the curtains" with Wednesday and they stay gone for over a month.

Can anyone explain this to me? Am I looking too much into it or is this something that's going to be important later?

If it's the second option, as this is my first read, please just answer "KEEP READING" and I'll do so.

Thanks guys.

Btw, I'm not sure if I used the correct terms as I'm reading in portuguese version and the translation may vary. This is also Gaiman's prefered edition.
