The rain fell in endless gray sheets that night. Lights flickered weakly along the cobblestone streets below. A lone figure hurried past the abandoned clock tower silently. Sherlock Holmes adjusted his coat against the biting wind sharply. Dr. Watson clutched his medical bag tightly beneath his arm securely. The note burned in Holmes’ pocket like a secret scar. Footsteps echoed hollowly in the empty alley behind them. A shadow shifted briefly behind the fog-laden windows upstairs. The woman’s scream tore through the silence suddenly then vanished. A single gunshot rang out crisp and final in the dark.
