"What shall we do?" I shook him roughly by the shoulder. "Is a gun any use?"

"No, no. The power will pass. Then it will end."

"You might have killed us all – you unspeakable fool – with your infernal experiments."

"I did not know. How could I tell that it would be frightened? It is mad with terror. It was his fault. He struck it."

Harvey Deacon sprang up. "Good heavens!" he cried. A terrible scream sounded through the house.

"It's my wife! Here, I'm going out. If it's the Evil One himself I am going out!"

He had thrown open the door and rushed out into the passage. At the end of it, at the foot of the stairs, Mrs. Deacon was lying senseless, struck down by the sight which she had seen. But there was nothing else.

With eyes of horror we looked about us, but all was perfectly quiet and still. I approached the black square of the studio door, expecting with every slow step that some atrocious shape would hurl itself out of it. But nothing came, and all was silent inside the room. Peeping and peering, our hearts in our mouths, we came to the very threshold, and stared into the darkness. There was still no sound, but in one direction there was also no darkness. A luminous, glowing cloud, with an incandescent centre, hovered in the corner of the room. Slowly it dimmed and faded, growing thinner and fainter, until at last the same dense velvety blackness filled the whole studio. And with the last flickering gleam of that baleful light the Frenchman broke into a shout of joy.

"What a fun!" he cried. "No one is hurt, and only the door broken, and the ladies frightened. But, my friends, we have done what has never been done before."

"And as far as I can help," said Harvey Deacon, "it will certainly never be done again."

And that was what befell on the 14th of April last at No. 17 Badderly Gardens. I began by saying that it would seem too grotesque to dogmatise as to what it was which actually did occur; but I give my impressions, our impressions (since they are corroborated by Harvey Deacon and John Moir), for what they are worth. You may, if it pleases you, imagine that we were the victims of an elaborate and extraordinary hoax. Or you may think with us that we underwent a very real and a very terrible experience. Or perhaps you may know more than we do of such occult matters, and can inform us of some similar occurence. In this latter case a letter to William Markham, 146M, The Albany, would help to throw a light upon that which is very dark to us.
