"Very good. Good-night, sir," said Coates; and performing a smart about-turn, he walked out of the room.
I went on reading, not in quest of any particular information, but in that idle mood when one reads anything, interesting or otherwise. For a time I heard my conscientious batman fastening doors and windows as was his nightly custom; then the door of his own room closed and I heard him no more.
When I first became aware of the howling of distant dogs I know not; but it was with a great start that I was aroused from my semi-reverie by the ringing of the door-bell. I realized that I had sat much longer than I had supposed. It was a quarter to one.
Gatton was my first thought; there must be an unexpected development in the case calling in some way for my services. Coates was a sound sleeper and evidently had not been awakened by the ringing of the bell; therefore, arrayed as I was in pajamas, slippers and bath-robe (for this, during the hot weather was my indoor costume) I walked out along the little corridor, unbolted the front door and opened it.
A woman stood there.
For a moment I thought foolishly that it was Isobel, and my heart gave a great leap. But the delusion was instantly dispelled when my visitor spoke.
Her voice had a totally different tone from that of Isobel—it was a low, almost caressing voice, with a vaguely husky note in it, fascinating in a way, yet although I found myself unable to account for the fact, vaguely uncanny—queer.
"Please excuse me," she said. "You will naturally wonder what has brought a visitor to your door at this hour of the night, and indeed my explanation is a strange one."
She glanced apprehensively over her shoulder as she spoke, out into the darkness of the roadway. I observed that she was apparently in evening dress and wore a very handsome cloak, having a thick silk scarf so draped about her head and shoulders that her face was quite concealed. Very clearly, now, I could hear the howling of dogs.
Instinct is a curious thing, and that which it prompted me to do at the moment when I found myself confronting this strange woman was promptly to awaken Coates! Honestly I was afraid of her and wished for nothing better than to have the closed door between us. This was all the more unaccountable as she had the appearance and manners of a cultured woman, presenting indeed a figure of great elegance as she stood there with her tall slender form outlined by the moonlight which slanted down through the trees to form a scimitar of light upon the path behind her.
