"That's enough, I guess, sir?" suggested the watchman. "These ladies mustn't be disturbed. All the rooms along here are occupied by old clients. You go back to your suite and if there's any thief we'll find him. But maybe you was dreamin'?"

I heard the key turn again in the lock; but I realised that unless I wanted to risk a row and perhaps arrest for "disorderly conduct," I must bow to circumstances. For a moment I was tempted to persist, but I thought how much more important than anything it was to be free from entanglements, and able to reach Jamaica before seven o'clock. "Spilt milk," I said to myself, and took the watchman's advice. But outside the forbidden door, I picked up a tiny rosetted slipper.

In my own rooms, I searched again for traces of a hostile presence. The collapsible box was a strange thing to find under a bed, but I couldn't prove that Little Red Riding Hood had been in it. Neither could I prove that a small pile of silver that I had poured out of my pockets on to the dressing-table had diminished, or that two letters which I had received—one from my brother Haslemere, one from Grace Odell—had been stolen. Nevertheless, while putting off my principal researches, I did telephone down to inquire who occupied rooms 212, 214. The man who answered from the office had "come on" since the people arrived, but, the name in the hotel register was "Mrs. W. Smith, nurse and child, Sayville, Long Island." Nothing could sound less offensive; but next morning when I descended at an unearthly hour it seemed that "the party" had already gone, by motor; and the man at the door "hadn't noticed no child." All I could do then was to reserve those rooms for myself, for two days, with orders that they should not be touched until investigated by me.

It lacked twenty minutes of train time when my chauffeur got me to Jamaica. This made me feel almost cheerful, but my heart sank as I reached the arrival platform. There were not many passengers, and even if there had been a crowd one figure would have stood out conspicuously—that of a tall woman in a grey dress, a long grey cloak, and a close-fitting grey bonnet with a thick grey veil falling over the face and breast. There was not a doubt in my mind but this was the formidable directress of the Grey Sisterhood, come in person to meet—I had almost said "her victim." If the woman had known of my plan she could hardly have found a better way of thwarting it.

As I glowered at the figure stalking up and down, I hated it. And I wondered if there were more than a coincidence in the fact that this was the third grey-veiled woman I had seen since last night. In the car at the theatre there had been too brief a glimpse to be sure of a resemblance, and the woman in 212 had left on my mind an impression of comparative shortness. But then, it is easy to stoop and disguise one's height, I told myself viciously, eager to find a connection between this woman and the others.

I could see nothing of her face, as we passed and repassed on the platform; but she was hovering not far off when I learned that the train from New York would be late. It was "hung up," a few miles away, owing to the breakdown of a "freighter." Instead of regret at this news, I felt joy. It gave me—with luck—a way out of my difficulty. Here was the Head Sister, waiting for Maida Odell; but if my car could get me to the delayed train before it was restarted only Maida herself could keep me from saying what I had come to say.

There wasn't a moment to waste, and I didn't waste one. Thinking I had won the first point in the game, I hurried to my car without glancing back at the veiled woman. I gave directions to West and was about to get into the auto, when a look in the chauffeur's eye made me turn. Close behind stood the grey lady. There was no doubt that her purpose was to speak to me. I took off my hat and faced her; but it was like trying to look at the moon through a thick London fog.

"You are Lord John Hasle, I believe?" she said, in a resonant contralto voice, with a slight suggestion of foreign accent. "I have heard of you," she went on. "You have been pointed out to me, and I know of your acquaintance with the Odells. You are going to motor back along the line. Your inquiries told me that. I would thank you, and so would Miss Odell, for taking me to her in your car."

Here was a situation! Rudely to refuse a favour asked by a lady, or—to lose, for ever, perhaps, my one hope? I chose to be rude. I stammered that I meant to go at such a pace it would be risking her life to grant the request. Very sorry; more lifting of the hat; a sheepish look of feigned regret; and then West, thoroughly ashamed of me, started the car. The next moment we had shot away, but not without a startling impression.

"The worst turn you can possibly do Miss Odell will be to prevent her coming into the Sisterhood House. It is the one place where she can be safe." Those were the words I heard over the noise of the starting motor; and as we left the tall statue of a woman, the high wind blew her thick veil partly aside. Instantly she pulled it into place; but I had time to see that the face underneath was covered with a grey mask. The effect on my mind of this revelation was of something so sinister that I felt physically sick. What could be the motive for such double precautions of concealment? Was it merely to hide a disfigurement, I wondered, or was there a more powerful reason? I determined to tell Miss Odell what I had seen.
