The gardenias bloomed too early this year, pale and silent. Moonlight traced the flagstone path like a deliberate, silver clue. Her body lay beneath the wrought-iron bench, impossibly still, posed. A single white petal rested precisely on her unblinking eye. I noticed the library window was open just a crack. From there, the heavy scent of old books drifted out. The front door, however, was bolted from the inside, securely. No footprints marred the damp soil of the flower beds. No sound disturbed the heavy, perfumed stillness of the night. I knew then that this murder had been perfectly designed.
