"I wish I could think so, miss," the girl went on. "But it wasn't a bit like anybody in the house. It was short and thick with enormously long arms and thin crooked fingers. I watched it for some time. I would have called out if I only dared. And then when it vanished I was ashamed to speak. But it was there all the same. Don't leave me, miss."

The last words came in a beseeching whisper. With a feeling of mingled impatience and sympathy Beatrice glanced round the room. A glass and a bottle of medicine stood by the bedside.

"I declare you are all alike," Beatrice exclaimed. "If you go to a dispensary and get free medicine you swallow it like water. But when a regular doctor prescribes it in this fashion you won't touch it. Now I am going to give you your draught at once."

The girl made no protest. Apparently she was ready to do anything to detain Beatrice by her side. She accepted the glass and swallowed the contents. A moment or two later she closed her eyes and in five minutes was fast asleep. As the medicine was a sleeping draught Annette would not wake before morning. Closing the door behind her Beatrice crept back to her room, looking fitfully over her shoulder as she walked along. She had caught something of Annette's nameless dread, though she strove to argue with herself about its absurdity. She glanced over the balustrade and noted the lights in the hall below. Seemingly her guardian had not retired. She found herself wondering if Wilfrid Mercer was still in the house. At any rate, it was pleasant to think there was help downstairs if necessary.

"I'll go to bed," Beatrice resolved. "I dare say I shall have forgotten this nonsense by the morning. That is the worst of an old house like this; these gloomy shadows appeal so to the imagination."

Nevertheless, Beatrice dawdled irresolutely before the fire. As yet she had not closed the door. She would go out presently and see that her dog was in his accustomed place. Usually he was as good as half-a-dozen guardians.

As Beatrice stood there she began to be conscious that the room was becoming filled with a peculiar, sweet odour, the like of which she had never smelt before. Perhaps it came from her flowers. She would go and see. She stepped out in the darkness and paused half hesitating.

CHAPTER VIII

THE BLUE TERROR

The strange sickly scent went as swiftly as it had come. The air cleared and sweetened once more. It was very odd, because there was no draught or breath of air to cleanse the atmosphere. Doubtless the scent had proceeded from the tropical flowers at the end of the corridor. Many new varieties had been introduced recently, strange plants to Beatrice, some of them full of buds which might open at any moment. Perhaps one of these had suddenly burst into bloom and caused the unfamiliar odour.
