The day after Boxing Day brought a frost so severe that the water pipes froze solid throughout London, and the breath of the horses in Baker Street rose like steam from a locomotive. Inside number 221B, the temperature was kept at bay by a monumental fire, though the atmosphere was heavy with the fumes of the foul shag tobacco Holmes was smoking. He spent the morning sorting through a mountain of old case files, while I attempted to keep my hands warm by wrapping them around a mug of hot coffee.
"It is a fascinating study, Watson," Holmes remarked, tossing a bundle of papers onto the table. "How easily a rustic mind turns to the supernatural when the nights are long and the snow is deep. The winter season is the absolute breeding ground for ghosts, ghouls, and legends."
"Surely you do not believe in such things," I replied with a smile.
"I believe in human malice and human greed, Watson. They are far more terrifying than any phantom. But look here—our holiday peace is about to be shattered."
A heavy, frantic step sounded upon the stairs, and the door was thrown open by a middle-aged gentleman in a heavy tweed coat. His face was flushed with exertion, and his boots were encrusted with the white chalk dust of the Sussex downs.
"Mr. Holmes!" he cried, clutching the back of a chair to steady himself. "You must come at once. The Yuletide Wraith has struck again, and Lord Blackwood lies dead in his study!"
"Pray compose yourself, sir," Holmes said, his eyes narrowing with immediate interest. "You have taken the early train from Lewes, your hands are stained with the ink of a country solicitor, and your name, if I am not mistaken, is Mr. John Bennett."
"Yes, sir! I am the family lawyer," the man gasped. "Lord Blackwood was found dead this morning at Blackwood Manor. The room was locked from the inside, the windows barred, and upon the snow outside the window—where no human could have stood without leaving prints—there were only the ancient, hoof-like marks of the Wraith!"
"A locked-room mystery with a supernatural garnish," Holmes murmured, a grim smile playing on his lips. "Watson, fetch your service revolver and your heaviest coat. The Sussex air will be biting, but the game is afoot!"
Three hours later, our train deposited us at a lonely station amidst the rolling, snow-covered hills of Sussex. A dogcart conveyed us to Blackwood Manor, a grim, Elizabethan structure surrounded by ancient oaks. We were met by the late Lord’s young nephew, Charles Blackwood, who was trembling with fear.
"It is the curse, Mr. Holmes," Charles whispered as he led us into the grand library. "The legend states that whenever a Lord Blackwood is to die at Christmas, the Yuletide Wraith leaves its tracks beneath the window. My uncle laughed at the old tales, and now he is gone."
Holmes ignored the young man’s terror. He went straight to the large bay window and peered out at the pristine snow. True to Bennett's word, a series of strange, cloven impressions ran parallel to the stone wall, stopping directly beneath the study window, with no returning tracks.
"Remarkable," Holmes muttered, opening the window and leaning out. He inspected the stone sill with his pocket lens, then turned his attention back to the room. Lord Blackwood’s body had been removed, but the heavy oak desk remained exactly as it had been found, a half-empty glass of mulled wine still sitting upon the blotter.
Holmes picked up the glass, sniffed it, and then dipped his finger into the dregs, touching it to his tongue. His eyes flashed with sudden, cold lightning.
"Watson, what do you make of the window lock?" Holmes asked.
I examined the iron latch. "It is a standard spring-bolt, Holmes. If the window were slammed shut from the outside, it would automatically lock itself."
"Precisely," Holmes said. "And what of the tracks? Look closer at the depth of the impressions, Watson. The snow is drifted deep, yet these 'hoof prints' are perfectly uniform in depth, regardless of the slope of the ground."
"What does that mean?" Charles Blackwood asked, stepping forward nervously.
"It means, young man, that the tracks were not made by a creature walking on the ground at all," Holmes snapped, walking toward the large fireplace. He reached up into the soot of the chimney and withdrew a long, sturdy bamboo pole. To its tip, a heavy, carved wooden block shaped like a goat's hoof had been securely lashed.
"An ingenious mechanism," Holmes explained, holding up the pole. "The murderer stood safely inside this very room, leaned out of the window, and pressed this pole into the snow to create the illusion of a phantom approaching the house. He then poisoned his uncle's wine, stepped out of the window, slammed it shut so the spring-bolt would catch, and walked away."
"But Holmes!" I objected. "If he stepped out of the window, where are his own footprints?"
"He did not step onto the ground, Watson. Look at the ancient ivy climbing the wall outside. The thick, wooden vines are as strong as a ladder. A nimble man could easily climb down the ivy, step onto the stone garden wall, and escape without ever touching the snow." Holmes turned his piercing gaze upon Charles Blackwood. "A nimble man, perhaps, who has spent his youth climbing the hills of Sussex, and who stood to inherit the Blackwood fortune the moment his uncle died."
The young man’s face turned the color of the snow outside. He made a desperate move toward the door, but I anticipated his flight, stepping into his path and pinning his arms firmly behind his back.
"It is useless, Charles," Holmes said softly. "The ink on your cuffs matches the soot on this pole, and the local apothecary will soon confirm that you purchased the aconite that laced your uncle's festive cup."
By the time the county constabulary arrived to take the wretched young man into custody, the winter twilight had deepened into a brilliant, starlit night. Holmes and I stood on the porch of the manor, watching the carriage depart into the darkness.
"A modern tragedy cloaked in an old legend," I observed, buttoning my coat against the chill.
"Indeed, Watson," Holmes replied, looking up at the winter stars. "It serves as a stark moral for this holiday season. Man may invent phantoms and wraiths to terrify his neighbors, but the truest evil always lies within the human heart. Those who invoke the dark legends of the past to cloak their modern greed will find that justice cannot be blinded by superstition. True peace at Christmastide belongs only to those who live with an open heart and a clear conscience."
