The rain drummed against the study window while Arthur slumped over his mahogany desk with a silver letter opener protruding. His blood dripped slowly onto the expensive Persian rug, creating a dark, widening pool in the dim, flickering lantern light. Nobody had heard the fatal strike, but the heavy scent of bitter almonds lingered in the stale, humid night air. Detective Thorne adjusted his damp coat, stepped carefully across the threshold, and sighed at the messy scene before his eyes.
