The body lay crumpled at the foot of the grand oak stairs, a silent accusation against the old manor. Detective Miller knelt beside it, his flashlight slicing through the dusty manor gloom like a question. The victim’s evening dress was torn at the shoulder, a single pearl earring glinting in the dim light. Across the hall, the library door stood ajar, revealing a desk with disarrayed papers and an open decanter. A shadowy figure watched from the upstairs balcony, then retreated quickly into the darkness of the second-floor corridor.
