(HELP I CAN'T FIND AN ANSWER) Neither spoke, but lay silently listening to the ticking of the clock. A stair creaked, and a squeaky mouse scurried noisily through the wall. The darkness was oppressive, and after lying for some time screwing up his courage, he took the box of matches, and striking one, went downstairs for a candle.

At the foot of the stairs the match went out, and he paused to strike another; and at the same moment a knock, so quiet and stealthy as to be scarcely audible, sounded on the front door.

The matches fell from his hand and spilled in the passage. He stood motionless, his breath suspended until the knock was repeated. Then he turned and fled swiftly back to his room, and closed the door behind him. A third knock sounded through the house.
