Rain hammered the conservatory roof while Detective Mara Quinn stared at the shattered, blood-stained glass below in absolute silence tonight. The victim, renowned botanist Julian Crowe, lay twisted among rare orchids, his throat punctured by pruning shears still dripping crimson. He had been dead for hours, yet the greenhouse thermostat insisted the room was freezing cold despite midsummer heat outside. This was no accident, Quinn thought, noting muddy footprints leading toward the locked pantry door nearby where someone breathed quietly. She drew her flashlight, whispered for backup, and slowly pushed the pantry door open wide revealing not escape but horror.
