"The real cause of her death was never known, but I obtained evidence
to show that on the night after the wing of a bat had been attached to
her hut, she wandered out in her sleep and visited the Black Belt. Can
you doubt that someone was calling her?"

"Calling her?"

"Mr. Harley, she was obeying the call of M'kombo!"

"The _call_ of M'kombo? You refer to some kind of hypnotic
suggestions?"

"I illustrate," replied the Colonel, "to help to make clear something
which I have to tell you. On the night when last the moon was full--on
the night after someone had entered the house--I had retired early to
bed. Suddenly I awoke, feeling very cold. I awoke, I say, and where do
you suppose I found myself?"

"I am all anxiety to hear."

"On the point of entering the Tudor garden--you call it Tudor garden?--
which is visible from the window of your room!"

"Most extraordinary," murmured Harley; "and you were in your night
attire?"

"I was."

"And what had awakened you?"
