Need help remembering Episode # of Detective Conan episode.

[Rydeft]

I want to start watching it again however I'd rather not start over. I think it was one of the last ones shown on adult swim however I do not know

Spoiler

Conan was sick, I remember he had a hat on most of the episode. He was separate from everyone else laying in a room with a window and a bookcase I believe. I think they were at some kind of mountain hotel or something. The preview for the next episode showed Conan a teenager again.

That's really all I remember. Sorry if this isn't enough detail.
