In White Raiment by William le Queux

The house was one of no mean order, and a glance at the rows of books showed them to be well chosen -- evidently the valued treasures of a studious man. Upon the writing-table was an electric reading-lamp with green shade, and a fine, pale photograph of a handsome woman in a heavy silver frame. In the stationery rack upon the table the note-paper bore an embossed cipher surmounted by a coronet.

After a few moments the door re-opened, and there entered a very thin, pale-faced, slightly-built man of perhaps sixty, carefully dressed in clothes of rather antique cut. He threw out his chest in walking, and carried himself with stiff, unbending hauteur. His dark eyes were small and sharp, and his clean-shaven face rendered his aquiline features the more pronounced.
