Footsteps rushed towards the source. There, an opulent room lay locked from within. A body, lifeless, abandoned suddenly. Mystery shrouded the air, chilling to the bone.

No murder weapon, no fingerprints, no eyewitnesses. A puzzle within a paradox. Trent, relentless, began meticulously unraveling the enigma.
