Great Moments in Fabric Literature, Vol XIV

He walked up the spiral staircase to the first floor, where Diana lived: a little sitting-room with her bedroom opening out of it, the whole communicating with the rest of the house by a long corridor that opened into the main staircase. There was no one in the sitting-room. He sat down on the sofa and looked attentively at the gold-thread embroidery of a sari that was being turned into a European dress. Under the golden light of the lamp gold tigers tore a Company's officer lying on the ground with a brandy-bottle in his hand: sometimes in his right hand, sometimes in his left, for the pattern had many variations.
