The rain-slicked cobblestones gleamed under the flickering gaslight, casting long, wet shadows. A single, bloodied glove lay abandoned near the edge of the alleyway. Inspector Hartwell knelt, his gloved fingers tracing the damp, crimson-stained leather with care. Above, a window slammed shut, its sudden bang swallowed by the city's hum. The victim's name was known to me, a secret I should have kept hidden.
