Anh turned into a wing of the house which was quite deserted and silent. At the end of it a shut door confronted her. She opened it softly. It was all dark within. But enough light entered from the corridor to show her the high bookcases ranged against the walls, the position of the furniture, and some dark, heavy curtains at the end. She was the first, then, to come to the meeting. She closed the door behind her and moved slowly and cautiously forwards with her hands outstretched, until she felt the curtains yield. She passed in between them into the recess of a great bow-window, opening on to the park; and a sound, a strange, creaking sound, brought her heart into her mouth.

Someone was already in the room, then. Somebody had been quietly watching as she came in from the lighted corridor. The sound grew louder. Ann peered between the curtains, holding them apart with shaking hands, and through that chink from behind her a vague twilight flowed into the room. In the far corner, near to the door, high up on a tall bookcase, something was clinging-something was climbing down. Whoever it was, had been hiding behind the ornamental top of the heavy mahogany bookcase; was now using the shelves like the rungs of a ladder.

This is a suspenseful scene! To enhance it, I can create some visuals and sounds. Would you like me to generate an image, a short video clip, or a sound effect to accompany this passage? Or perhaps all three?
