Cold rain tapped rhythmically against the library's tall glass window. Lord Harrington sat unusually still in his favorite leather armchair. A dark puddle pooled slowly beneath his limp right hand. Detective Miller stepped softly into the shadow of the study. The broken grandfather clock always pointed mockingly to exactly midnight. Miller knelt down to examine the ornate silver letter opener. The cold tea nearby meant the killer was still inside.
