There came a great burst of thunder. It was the last of the storm.
It bellowed and shuddered, went, and came rolling up again. It died away at last in the great distance, with a low continuous rumbling as if it would never cease. The silence that followed was like the Egyptian darkness; it might be felt.
Out of the tense heart of the silence came a faint sound. It came again and again, at regular intervals.
"That is my uncle's step!" said Arctura in a scared whisper through the dark.
It was plainly a slow step--far off, but approaching.
"I wonder if he has a light!" she added hurriedly. "He often goes in the dark without one. If he has you must get behind the altar."
"Do not speak a word," said Donal; let him think you are asleep. If he has no light, I will stand so that he cannot come near the bed without coming against me. Do not be afraid; he shall not touch you."
The steps were coming nearer all the time. A door opened and shut.
Then they were loud--they were coming along the gallery! They ceased. He was standing up there in the thick darkness!
"Arctura," said a deep, awful voice.
It was that of the earl. Arctura made no answer.
"Dead of fright!" muttered the voice. "All goes well. I will go down and see. She might have proved as obstinate as the boys' mother!"
Again the steps began. They were coming down the stair. The door at the foot of it opened. The earl entered a step or two, then stopped.
Through the darkness Donal seemed to know exactly where he stood. He knew also that he was fumbling for a match, and watched intently for the first spark. There came a sputter and a gleam, and the match failed. Ere he could try another, Donal made a swift blow at his arm. It knocked the box from his hand.
"Ha!" he cried, and there was terror in the cry, "she strikes at me through the dark!"
Donal kept very still. Arctura kept as still as he. The earl turned and went away.
"I will bring a candle!" he muttered.
"Now, my lady, we must make haste," said Donal. "Do you mind being left while I fetch my tools?"
"No--but make haste," she answered.
"I shall be back before him," he returned.
"Be careful you do not meet him," said Arctura.
There was no difficulty now, either in going or returning. He sped, and in a space that even to Arctura seemed short, was back. There was no time to use the file: he attacked the staple, and drew it from the bed-post, then wound the chain about her arm, and tied it there.
He had already made up his mind what to do with her. He had been inclined to carry her away from the house: Doory would take care of her! But he saw that to leave the enemy in possession would be to yield him an advantage. Awkward things might result from it! the tongues of inventive ignorance and stupidity would wag wildly! He would take her to her room, and there watch her as he would the pearl of price!
"There! you are free, my lady," he said. "Now come."
He took her hands, and she raised herself wearily.
"The air is so stifling!" she said.
"We shall soon have better!" answered Donal.
"Shall we go on the roof?" she said, like one talking in her sleep.
"I will take you to your own room," replied Donal. "--But I will not leave you," he added quickly, seeing a look of anxiety cloud her face, "--so long as your uncle is in the house."
"Take me where you will," rejoined Arctura.
There was no way but through the crypt: she followed him without hesitation. They crept through the little closet under the stair, and were in the hall of the castle.
As they went softly up the stair, Donal had an idea.
"He is not back yet!" he said: "we will take the key from the oak door; he will think he has mislaid it, and will not find out that you are gone. I wonder what he will do!"
Cautiously listening to be sure the earl was not there, he ran to the oak door, locked it, and brought away the key. Then they went to the room Arctura had last occupied.
The door was ajar; there was a light in the room. They went softly, and peeped in. The earl was there, turning over the contents of her writing-desk.
"He will find nothing," she whispered with a smile.
Donal led her away.
"We will go to your old room," he said. "The whole recess is built up with stone and lime: he cannot come near you that way!"
She made no objection. Donal secured the doors, lighted a fire, and went to look for food. They had agreed upon a certain knock, without which she was to open to none.
