All About Dogs: Peggy's Place

I read it last year in English class, and I liked it, but I can’t remember the title.

This 17-year old boy moves to Bath, UK (I think it was) and he sees this inn. He goes to knock on the door, and this lady opens it immediately (she was waiting for him) and he stays there for a while, and when he checks in he notices that only two other people had ever stayed at the inn. Well, anyway, at the end the lady gives him some tea, and he thought it smelled funny. He starts talking about the 2 other guys who stayed at the inn, and the lady replies that they are still upstairs. And the ladies’ dog was stuffed [taxidermy] so you know when the lady said that the 2 guys are still upstairs, she meant she killed and then stuffed them. And then it’s sort of a cliffhanger because it doesn’t say if the boy dies or not.

Lol, I know it’s sort of weird. v_v
Does anyone know the name of it? =O

Thanks if you know!! =D
Thank you so much Mary M!! I was starting to get a little frustrated! =D
