Detective Mara Quinn arrived before sunrise, coffee steaming bitter cold. The mansion's marble foyer held one shattered crystal chandelier silently. Beneath it lay Victor Hale, perfectly still, eyes unnervingly open. No blood pooled, no footprints marked the pristine white floor. Someone had arranged his cufflinks into a tiny clock face. It read three fifteen, but his watch showed midnight exactly.
