The cold rain hammered hard against the tall library windows as Detective Sarah Chen stepped over the broken glass carefully. Professor James Whitfield lay sprawled out beneath the towering oak bookshelves, his tweed jacket soaked dark with sticky crimson blood. A heavy brass candlestick had rolled far underneath the mahogany desk, its polished base smeared with something terrible and red. Sarah knelt down beside the body, noting how his fingers still clutched a torn page from some ancient manuscript book. The ugly wound on his temple told her everything about the weapon, the angle, and the killer's surprising physical strength. Someone had searched the entire office thoroughly, pulling every drawer out completely and scattering papers across the expensive Persian rug. Yet the wall safe behind the faded portrait of Aristotle stood open, empty, and completely untouched by gloved human hands. Whatever the old professor had been hiding there, the killer had surely known exactly where to look for it earlier. Sarah photographed the bloody scene methodically, capturing every detail from the toppled ink bottle to the shattered antique reading lamp. Outside, sudden lightning illuminated the university quadrangle where a lone figure in a black coat hurried toward the parking lot. Sarah never saw the retreating figure, but she could feel someone watching her from somewhere deep in the darkened stacks. Hidden among the ten thousand silent books, a murderer waited patiently to learn exactly what the young detective already knew.
