Sir James Walter

"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 gray in the service, is a gentleman, a favoured guest in the most exalted houses, and, above all, a man whose patriotism is beyond suspicion." (Mycroft Holmes)
The house of the famous official was a fine villa with green lawns, stretching down to the Thames. As we reached it the fog was lifting, and a thin, watery sunshine was breaking through. A butler answered our ring.
“Sir James, sir!” said he with solemn face. “Sir James died this morning.”
