J. Campbell - Gaslight Arcanum - Uncanny Tales of Sherlock Holmes

I was grateful for what little light came from the gas lamps around the walls, but their flame only accentuated the shadows in the tall empty hall. Four large copper vats dominated the large room. The air smelled almost sweet, with a hint of bitterness where fresh hops joined the tang of fermentation. Beneath these well-remembered odors I also sensed something new — a hint of the same acrid tang that had assaulted my nasal passages back in Holmes’ room. Before I stepped further than the doorway I peered into all the corners, searching for any trace of the luminescence. I found none. Nevertheless it was with some trepidation that I stepped inside.

It was obvious to me that someone had deliberately introduced a poisonous material into the brewing vats. Their reason was as yet unclear to me, but the thought that this might have been going on for some time made my blood run cold. There might even, at this very moment, be drinkers quaffing tainted ales all across the capital. In my mind’s eye I saw the slime seethe in the flagons, saw the terror in the drinkers’ eyes as the contagion took them and started to feed. The fear of the consequences strengthened my resolve. I moved further inside.

A cloud moved. Suddenly moonlight washed through the hall from above. It made my search somewhat easier. I found nothing around the nearer of the two vats and almost relaxed. That all changed when I rounded the third vat and almost walked into a mist of green luminescence. As I moved closer I saw that it rose from a body on the floor — the remains of what had been a man, but was now a seething mass of green protoplasm. The slime seemed to notice my presence and began to slump and flow over the brewery floor, moving so quickly that I was forced to take several steps backwards.

My retreat was halted as the luminescence swelled and flared, engulfing me in a globe of dancing light. At once I felt calm, almost serene. Shadows flitted around me, wraiths made of little more than thin green fog. I felt no fear, no compulsion to run — merely the innocent curiosity of a child. I stepped forward towards the rolling carpet of green.

The arrival of my friend Sherlock Holmes saved my life. All he did was place a hand on my shoulder, but that was sufficient to break the spell under which I had been placed. I looked down to see the green slime merely inches from my brogues and getting closer.

Holmes stepped forward and threw a handful of white powder over the green carpet. It immediately retreated, black pustules bubbling and bursting across the surface. My eyes started to sting and water. Holmes turned and smiled grimly, showing me another handful of white powder.

“Caustic soda,” he said. “It seems to be efficacious.”

He wore a canvas satchel over his shoulder. It gaped wide, showing it to be crammed full with the powder. Before I could inquire further Holmes strode away from me, following the retreating slime.

“Come Watson,” he called. “Let us beard Grendel in his lair.”

I followed, keeping a safe distance from the scattering of lye.

The slime dragged itself away before the powder. A high, fluting cacophony echoed and whistled around us, as if the bubbling pustules screamed in agony. Within seconds Holmes had the remains of the creature cornered under the copper vat in the leftmost rear of the brewery.

Holmes continued to throw handfuls of lye, at the same time calling out to me over his shoulder.

“Watson. I have need of your old pen-knife.”

I moved forward, following Holmes’ gaze. There was a large dent in the tun just above head height. Deep inside was a small lump of darker material, like a pebble embedded in the copper.

I took out my knife and started to work the lump free while Holmes kept the carpet of slime at bay. I was so intent on my task I did not notice the new arrivals on the brewery floor, only becoming aware of them when Holmes called out in despair.

“No. Not yet!”

I managed to free the pebble and dropped it into my waistcoat pocket. I turned to see three men clad in oilskins standing behind Holmes. They each carried long hoses and were spraying the floor all around. Suddenly the place smelled less like a brewery and more like a hospital as soap and bleach washed over our feet.

My brogues were ruined, as were Holmes’ leather boots, but he had not yet noticed. His gaze was fixed on a drain in the center of the floor. It sat in a slight dip, so that all spillage would flow towards it. The pressure from the hoses washed across the slime and sent it sailing in bubbling foam.

“Stop!” Holmes called, but it was too late. The last hint of the green substance disappeared down to the sewers below.

We found Lestrade out in the street coordinating proceedings. The hosing down of the brewery went on for several hours while we stood outside, smoking and keeping an eye out for any return of either the slime or the luminescence. After a time Lestrade announced himself satisfied and called off the clear up. Holmes proved harder to satisfy. He insisted on waiting until almost dawn, spending the intervening hours stalking the floor and peering in every corner of the brewery. Twice he asked to see the pebble I had dug from the vat. Both times he returned it to me with a grunt of displeasure. The sun was throwing an orange tinge across the sky before I was finally able to persuade him to leave.

He said nothing in the carriage on the journey to Baker Street, merely sat, elbows on his thighs and fingers steepled at his lips, deep in thought.

Mrs. Hudson ministered to our hunger, providing a hearty breakfast that I took to with gusto. Holmes scarcely ate a mouthful. He had already taken the pebble from me, and pored over it intently, subjecting it to a variety of assays and investigations. By the time I finished my breakfast he seemed to have come to some conclusions. He called me over and handed me a magnifying lens.

“I believe we have found our source,” he said to me. I immediately saw what he meant. The pebble was a small rough stone. Holmes had managed to slice it in half and I looked down at the inner hemisphere. There was a small hollow almost dead center, hardly bigger than my little finger nail. It carried the barest tinge of green.

“The stone itself is mostly iron,” Holmes said. “With a trace of nickel. I do believe you are holding your first visitor from beyond this world.”

After that Holmes seemed to settle somewhat. We sat by the fire and lit our pipes. He repeatedly quizzed me on my experience inside the luminescence.

“It was dashed peculiar Holmes,” I said. “I have experienced something similar before, while watching a Swami perform the rope trick in Delhi, but even there I felt in control. This time it felt like my very will had been drained from me. If you had not intervened, I do believe I would have given myself to it.”

Holmes nodded, and went back to staring into the fire.

I left in the early morning to fulfill an obligation to a sick friend. When I returned Holmes was scarcely in any better spirits. I found him on the doorstep, delivering instructions to a group of urchins who were gathered around him as he distributed pennies.

As I entered I saw Mrs. Hudson packing cleaning materials back into the cupboard.

“Please Doctor. Can you not get him to settle? He’ll be the death of me with all this commotion.”

Holmes seemed oblivious to his landlady’s protestations.

“We must be vigilant,” he said, as we once more sat by the fire. “As a doctor you well know the dangers of contagion re-emerging after a period of dormancy.”

I saw that a black mood had descended on my friend, one that only action might shift, but there was no news forthcoming. In the late afternoon I went to stoke the fire. I searched for the old pair of bellows I customarily used, but they were nowhere to be found, and Holmes merely smiled at my mention of them.
