[Illustration: "I ... TRIED A STEP TOWARD THE STAIRS, WITH EYES ALERT FOR ANY MOVEMENT OF THE MASTIFF."]
I cut straight across the heather towards the light, risking quags and pitfalls. Nay, so heartening was the chance to hear a fellow-creature's voice that I broke into a run, skipping over the stunted gorse that cropped up here and there, and dreading every moment to see the light quenched. "Suppose it burns in an upper window, and the family is going to bed, as would be likely at this hour"--the apprehension kept my eyes fixed on the bright spot, to the frequent scandal of my legs, that within five minutes were stuck full of gorse-prickles.
But the light did not go out, and soon a flicker of moonlight gave me a glimpse of the house's outline. It proved to be a deal more imposing than I looked for--the outline, in fact, of a tall-square barrack with a cluster of chimneys at either end, like ears, and a high wall, topped by the roofs of some outbuildings, concealing the lower windows. There was no gate in this wall, and presently I guessed the reason. I was approaching the place from behind, and the light came from a back window on the first floor.
The faintness of the light also was explained by this time. It shone behind a drab-colored blind, and in shape resembled the stem of a wine-glass, broadening out at the foot--an effect produced by the half-drawn curtains within. I came to a halt, waiting for the next ray of moonlight. At the same moment a rush of wind swept over the chimney-stacks, and on the wind there seemed to ride a human sigh.
On this last point I may err. The gust had passed some seconds before I caught myself detecting this peculiar note, and trying to disengage it from the natural chords of the storm. From the next gust it was absent. And then, to my dismay, the light faded from the window.
I was half-minded to call out when it appeared again, this time in two windows--those next on the right to that where it had shone before. Almost at once it increased in brilliance, as if the person who carried it from the smaller room to the larger were lighting more candles; and now the illumination was strong enough to make fine gold threads of the rain that fell within its radiance, and fling two shafts of warm yellow over the coping of the back wall into the night. During the minute or more that I stood watching, no shadow fell on either blind.
