Prove it

 Edward tightens his grip unto the cord and squeezes himself out of the window.

 He swings on thin air and little by little, he started slipping down the cord.

From outside, he heard the door sharp sound as it opens and footsteps starts to emerge in the room.

 Edward jumps down, leaving the rope and landing squarely on his side.

 "Oww" he groans out loudly but quickly close his mouth the moment he realize what just did.

 "I think I heard something"

Edwards eyes widen and he thought fast snought to get into an opening on the walls of the Castle.

 The people in the room where he just got out from, went to the same window he jumped out from and with a flashlight in their hand, they flashed several lights on the ground to see if someone is there or not.

 "So much for hearing something" one of them retorts and the voice that spoke earlier started mumbling some words beneath his breath. 

 Edwards releases a sigh of relief.
