When Mr White goes down to the parlor to fetch the paw, list the words create the tension.

From the text:

He went down in the darkness, and felt his way to the parlour, and then to the mantlepiece. The talisman was in its place, and a horrible fear that the unspoken wish might bring his mutilated son before him ere he could escape from the room seized up on him, and he caught his breath as he found that he had lost the direction of the door. His brow cold with sweat, he felt his way round the table, and groped along the wall until he found himself in the small passage with the unwholesome thing in his hand.
