My dearest Lily, Forgive me. I would be with you now, rather than closeted in my study, but I do not wish you or our children to witness my demise. I love you. I tell you now, so that you will know that my last thought was of you. I have placed my affairs in order -- do not fear, my love, you will be well provided for -- all that is required of my remaining time is to explain the events which have led to my death. Though the scene will seem so similar to my elder brother's death, I would not wish you to think I had taken my own life in the manner in which Edmund took his. When Dr V came to see me some weeks ago, he brought with him the bottle of strychnine that now sits empty upon my desk. He was in high spirits, because his latest alchemical experiment had been a success, and brought the strychnine in order to demonstrate the efficacy of his elixir. In truth, his very presence could be considered proof, since he had been dead earlier that morning, but, as I had not witnessed his revival, he wished me to see the results first hand. At his request, I summoned the chambermaid, while he prepared a syringe of strychnine. I thought he would ask her to procure a hen or some such thing for use in his demonstration however, when she arrived, Dr V-- plunged the syringe into her arm with no warning. I leapt from my chair, but before I could do more than cross the room, the strychnine took effect with results that horrified me. Even though I had complete confidence in Dr V's elixir, I could not restrain a cry of dismay as the chambermaid's head tilted back in a sudden convulsion. Her lips tightened, giving her the appearance of laughter and she dropped to her knees, clawing at her throat. Her back arched, pitching her over so that she lay with only her head and heels touching the carpet.
