```
And the raven, never flitting, still is sitting, still is sitting,
On the pallid bust of Pallas just above my chamber door;
And his eyes have all the seeming of a demon's that is dreaming,
And the lamplight o'er him streaming throws his shadow on the floor;
And my soul from out that shadow that lies floating on the floor
Shall be lifted nevermore!
```
The author creates suspense in this stanza through several techniques:
* Repetition: The repetition of the words "still is sitting" and "nevermore" creates a sense of foreboding and inevitability.
* Imagery: The image of the raven's "eyes have all the seeming of a demon's that is dreaming" is unsettling and suggests that the narrator is in the presence of something supernatural and malevolent.
* Atmosphere: The overall atmosphere of the stanza is one of darkness, mystery, and dread, which contributes to the sense of suspense.
The combination of these techniques creates a feeling of tension and unease in the reader, making them wonder what will happen next and what the ultimate fate of the narrator will be.
