Green Tea by Joseph Thomas Sheridan Le Fanu

I made him have candles lighted, and saw the room looking cheery and inhabited before I left him. I told him that he must regard his illness strictly as one dependent on physical, though subtle physical, causes. I told him that he had evidence of God's care and love in the deliverance which he had just described, and that I had perceived with pain that he seemed to regard its peculiar features as indicating that he had been delivered over to spiritual reprobation. Than such a conclusion nothing could be, I insisted, less warranted; and not only so, but more contrary to facts, as disclosed in his mysterious deliverance from that murderous influence during his Shropshire excursion. First, his niece had been retained by his side without his intending to keep her near him; and, secondly, there had been infused into his mind an irresistible repugnance to execute the dreadful suggestion in her presence.

As I reasoned this point with him, Mr. Jennings wept. He seemed comforted. One promise I exacted, which was that should the monkey at any time return, I should be sent for immediately; and, repeating my assurance that I would give neither time nor thought to any other subject until I had thoroughly investigated his case, and that tomorrow he should hear the result, I took my leave.
