The figure mounted the steps slowly, and as though in pain, passed gently by me with just such a movement of the air as a moth might make in its flight, and with a tiny sound as of a sigh turned to the left and retreated along the passage.
''Tis a lady!' I murmured to myself, overcome with astonishment.
Almost at once I heard a firm tread of feet upon the stairs below, and there mounting quickly another figure now showed at the head of the stairs, and I recognised in the half light that it was my uncle.
He did not pause, but turned at once to the left, and incontinently followed after the fragile figure of the lady, who had disappeared from view into the misty depth of the corridor.
I stood dumbfounded. Here was a double mystery which I felt bound, though a little shaken in my nerves, to unravel.
A-tiptoe I followed after my uncle along the dark passage, feeling my way lest I should knock against the pictures or the various bronze casts that stood on pedestals beside the wall.
The passage turned shortly again to the left and led, as I knew, past my uncle's bedroom to the muniment room situate at the end of the wing.
When I turned the corner there was just sufficient moonlight from the south window to show me the dim figure of my uncle standing within the muniment room, apparently feeling with his hands upon the wall.
As I stood irresolute, but keenly watchful, I saw the sudden purple flame of a match leap up in the darkling room. My uncle had lit a match, and with trembling, excited fingers was applying the flame to a candle that stood on the table.
He held the candle up towards the wall, peering intently upon it, and as I drew nearer on tiptoe I could hear him exclaiming in disjointed utterance.
