I gently closed the register, for I had no use of it tonight, and returned my attention to the letter. What worried me so? The edge of the parchment continued to catch my eye, as though something crawled beneath it. And the longer I remained at my table, the more my belly ached and my fingers trembled. In the distance, beyond the walls of the shop, the bells on a carriage sounded frighteningly similar to the chains on a constable's belt. But I assured myself that the bailiffs would not come tonight, just as they had not come for the last two decades. My shop, like my poisons, was too cleverly disguised. No man would find this place; it was buried deep behind a cupboard wall at the base of a twisted alleyway in the darkest depths of London.

I drew my eyes to the soot-stained wall that I had not the heart, nor the strength, to scrub clean. An empty bottle on a shelf caught my reflection. My eyes, once bright green like my mother's, now held little life within them. My cheeks, too, once flushed with vitality, were sallow and sunken. I had the appearance of a ghost, much older than my forty-one years of age.

Tenderly, I began to rub the round bone in my left wrist, swollen with heat like a stone left in the fire and forgotten. The discomfort in my joints had crawled through my body for years; it had grown so severe, I lived not a waking hour without pain. Every poison I dispensed brought a new wave of it upon me; some evenings, my fingers were so distended and stiff, I felt sure the skin would split open and expose what lay underneath.

Killing and secret-keeping had done this to me. It had begun to rot me from the inside out, and something inside meant to tear me open.

At once, the air grew stagnant, and smoke began to curl into the low stone ceiling of my hidden room. The candle was nearly spent, and soon the laudanum drops would wrap me in their heavy warmth. Night had long ago fallen, and she would arrive in just a few hours: the woman whose name I would add to my register and whose mystery I would begin to unravel, no matter the unease it brewed inside of me.
