Wow, that was an awesome game. It took me a lot of tries to figure out exactly what to do.
I did find one odd bug, though... one time after I said that I wanted to talk to Rolf after speaking to Bridget's mother, it took me to the screen where Crabtree asked if I had a suspect, so I said that the name wasn't on the list, said how Ted didn't have the bracelet, and told him about the paper Dr. Raleigh was writing. Then for whatever reason I was magically whisked away to Raleigh's colleague's office, I apparently had roughly -1 hours left, and it was impossible to leave.
PS: Why do I see a lot of people saying that Yale did it? He didn't; if you say he did it in the list of suspects Crabtree informs you he was somewhere else.
