The mahogany door groaned open, revealing the dim, book-lined study of the late Lord Harrington within. His body lay sprawled before the cold fireplace, the silver letter opener protruding from his chest. A single shattered glass lay near his hand, amber liquid staining the expensive Persian rug. Detective Miller stepped inside, the scent of old paper and fresh blood hanging heavy. He knelt, examining the victim’s frozen expression of absolute, profound shock before death.
