Shinichi Kudo by Mudou Setsuna

A good trick, but not the right one.
It was a good idea, that Heiji came up with. But unfortunatley, the string was a red herring. ;) Still, it did end up with the key in my pocket. Do you remember what the REAL trick the murder used was?

If we had the rest of the props, and a Heiji and a few extra people, I'd have recreated the whole mystery. Maybe next time. :D
