I finally figured out how to open the chest of drawers in Roberts room got all the stuff out of it.Ifollowed the rest of TallyHo's walkthru ,went to office and opened safe and all drawers read everything and took everything I could(have all 3 slides),but when I backed away from the safe the niece did not come thru the door I am standing there like dummy with nothing happening.Anyone else have this problem or what am I doing wrong

Daremo, did you read all of the documents in the safe, and take the slide viewer? Be very careful and almost pixel perfect to find one that you might have been over looking...
