Derelict House Footage
Location: Guest House, on the dresser next to the tape recorder.
Guide: The only trick to this one is that you start out standing on top of a lockpick. Take a step or two back, and look down to retrieve it. When the party enters the kitchen, use it on a locked drawer to your right. There's nothing good there now, but when you return to being Ethan, this drawer will contain an Antique Coin. Other than that, just follow along until the tape runs out.
