This is a BS Tantei Club - Yuki ni Kieta Kako video that was up on Stage6.
I downloaded it mere days before the site shut down. Unfortunately, I don't remember who the original uploader was.
This is the second episode.
EDIT Nov. 9, 2011: bluesun told me I mixed Chuuhen and Kouhen's titles up. Corrected.
