A paragraph followed which was doubly underlined, and pursuing my reading I made a discovery which literally caused me to hold my breath. This is what I read:
“In a recent contribution to the Occult Review, Mr. Colin Camber, the American authority, offered some very curious particulars in support of a theory to show that whereas snakes and scorpions have always been recognized as sacred by Voodoo worshippers, the real emblem of their unclean religion is the bat, especially the Vampire Bat of South America.
“He pointed out that the symptoms of one dying beneath the spell of an Obeah man are closely paralleled in the cases of men and animals who have suffered from nocturnal attacks of blood-sucking bats.”
I laid the open book down upon the bed. My brain was in a tumult. The several theories, or outlines of theories which hitherto I had entertained, were, by these simple paragraphs, cast into the utmost disorder. I thought of the Colonel’s covert references to a neighbour whom he feared, of his guarded statement that the devotees of Voodoo were not confined to the West Indies, of the attack upon him in Washington, of the bat wing pinned to the door of Cray’s Folly.
Incredulously, I thought of my acquaintance of the Lavender Arms, with his bemused expression and his magnificent brow; and a great doubt and wonder grew up in my mind.
I became increasingly impatient for the return of Paul Harley. I felt that a clue of the first importance had fallen into my possession; so that when, presently, as I walked impatiently up and down the room, the door opened and Harley entered, I greeted him excitedly.
“Harley!” I cried, “Harley! I have learned a most extraordinary thing!”
Even as I spoke and looked into the keen, eager face, the expression in Harley’s eyes struck me. I recognized that in him, too, intense excitement was pent up. Furthermore, he was in one of his irritable moods. But, full of my own discoveries:
“I chanced to glance at this book,” I continued, “whilst I was waiting for you. You have underlined certain passages.”
He stared at me queerly.
