but i understand you cant ask it with that phrasing.-could you begin by asking , is the diary in the house ? -ed was trying to organize his thoughts.-if the answer is yes , then you could begin asking if its on the first floor , second floor and so on.-then you could go on to pinpoint the room on that floor in the same manner.-is it in the family room ? -the library ? -etc.-if the answer is no , you could begin naming each building until you find the right one.-do you think that might work ?
