The clock above Blackwood Station stopped at midnight without warning. Rain polished the empty platform until it shone like glass. Inspector Mara Venn arrived beneath the station's flickering green lamp. The young porter pointed toward the train, unable to speak. The victim sat upright inside a carriage locked from within. His evening gloves were spotless, though his throat was slit. No weapon lay nearby, and every carriage window remained sealed. Mara touched his pale cheek; warmth lingered beneath her fingers. Upon his lap lay a dance card dated tomorrow evening. Every line was blank except the final waltz: Mara Venn.
