A perfect silent exit starts with the least obvious route—stairs, a service door, a vent that nobody checks. I always lace the getaway car with a bit of rubber for muffled wheels, slip a smoke pellet to mask any smell, and leave a quick distraction like a dropped ring that spins in the hallway, making the guards chase a phantom. Timing, a quick jump, and a clean cut of the last lock keep me off the radar.
