Back into the chamber turning, all my soul within me burning, Soon again I heard a tapping something louder than before.
"Surely," said I, "surely that is something at my window lattice;
Let me see, then, what thereat is and this mystery explore–
Let my heart be still a moment and this mystery explore;–
'Tis the wind and nothing more."
—"The Raven,"
Edgar Allan Poe

How does Poe create suspense in this stanza? 

by allowing the speaker to retreat from all danger

by revealing that the tapping is caused by the wind

by having the speaker explore the mysterious noise
