She and Allan by H. Rider Haggard

Like one who dreams I passed down the outer hall where stood the silent guards as statues might, and out through the archway. Here I paused for a moment, partly to calm my mind in the familiar surroundings of the night, and partly because I thought that I heard someone approaching me through the gloom, and in such a place where I might have many enemies, it was well to be prepared.

As it chanced, however, my imaginary assailant was only Hans, who emerged from some place where he had been hiding; a very disturbed and frightened Hans.
