The actual official guardian of the papers is the famous government expert , Sir James Walter , whose decorations and sub-titles fill two lines of a book of reference . He has grown grey in the service , is a gentleman , a favoured guest in the most exalted houses , and , above all , a man whose patriotism is beyond suspicion . He is one of two who have a key of the safe . I may add that the papers were undoubtedly in the office during working hours on Monday , and that Sir James left for London about three o'clock taking his key with him . He was at the house of Admiral Sinclair at Barclay Square during the whole of the evening when this incident occurred . '' `` Has the fact been verified ?
