Jane sat looking at the letter. It made her feel rather sick. If she had not come down, if she had shirked putting the papers back, if the letter addressed to Jeffrey Ember, Esquire, had reached Jeffrey Ember’s hands—well, it was a good enough death-warrant, and Molloy must have known that very well when he wrote it.

“It’s exactly like a Moral Tract,” said Jane. “I hated coming back, and I did it from a Sense of Duty, and this is the Reward of Virtue.”

She put the Reward of Virtue down rather gingerly on the bench beside her. She felt about touching it rather as she had felt when she touched the slug. She wanted to wash her hands. An odd creature Molloy. He had given her away exactly and completely, yet he had left her any small shred of protection which she might be supposed to derive from passing as his daughter.

Jane turned her thoughts from Molloy to the more pressing consideration of her own immediate course of action. Ember would come in the morning, and would find Molloy gone, and no word to say where he had gone, or why. The idea of following in Molloy’s footsteps presented itself vividly before Jane’s imagination. Why should she stay any longer at Luttrell Marches? The idea of getting away set her heart dancing. And what was there to stay for? She had all the evidence necessary to procure Ember’s arrest and the smashing of the conspiracy. The sooner she was out of Luttrell Marches and with her precious papers in a place of security the better. For a moment she contemplated taking the originals of the lists; Ember would naturally conclude that it was Molloy who had gone off with them. But on second thoughts she decided that it would be in the highest degree unwise to put Ember on his guard. His distrust of Molloy might be so great as to induce flight. She decided to leave the originals and to take the copies—but she had left the copies in her room pinned to the cupboard ceiling. Go back for them she could not. Even if she could have forced herself to the effort, the risk was too great. They must stay where they were, whilst she found Henry. The sooner she got off the better. She had no watch, but the night must be very far spent, and if Ember were to take it into his head to come back——

The bare idea brought Jane to her feet. She picked up her candle, lit it, and with feelings of extreme satisfaction set fire to Molloy’s letter, making a little pent roof of it like the beginning of a card house on the stone floor. She had often admired the way in which masses of compromising documents are consumed in an instant by the hero or heroine of the adventure novel. She used four matches before she considered that this particular letter was really harmless. The envelope took two more. Then she collected the ash very carefully, crumbled it up well, and scattered it amongst the rubble in the broken-down passage where Molloy had found her. Then, having taken a good look round to make sure that nothing compromising remained, she picked up her candle and passed through the gate, leaving the laboratory in darkness behind her. When she came to the turn she hesitated, and finally went straight on, following the passage which she had not yet explored, down which Molloy and Ember had come the day before. She was almost sure that it would lead back into the main corridor just short of the headland exit; but she had not gone more than a yard or two along it when she heard something that brought her heart into her mouth.

Almost as the sound reached her she had blown her candle out and was pinching the glow from the wick. For a moment the darkness was full of phantom tongue-shaped flames; then she stopped seeing them and saw instead a faint glow coming from the direction in which she herself had come on her way to the laboratory. Somebody was coming along the passage. If she had gone back by the same way that she had come, she would have met this somebody. As it was, she might escape notice. If the person were going to the laboratory, he would have to take a sharp turn to the left, a right-angled turn. The passage in which she was ran off at an acute angle, and the person approaching would have his back to her as he passed.

The glow became a beam. Next moment Ember passed without turning his head. Jane saw the back of his shoulder dark against the light from his torch, and caught a fleeting glimpse of his profile, just enough for recognition and no more. Indeed, it was the fur coat that she recognised as much as the man. She stood quite still whilst he switched on the electric light and passed into the laboratory, then she turned and walked away as quickly as she dared, feeling her way by the wall till a turn in the passage gave her enough courage to light her candle. She put the spent match in her pocket, looked ahead, and drew a sharp, almost agonised, breath.

About two feet from where she stood, and exactly in her path, was the black mouth of an uncovered well. Jane looked at it, and quite suddenly, she had no idea how, found herself sitting on the floor with hot wax running down her hand from the guttering candle. It seemed to be quite a little time before she could make sure of walking steadily enough to skirt the well. She went by it at last with averted head and fingers that, regardless of slime, clung to the wall.

As she had expected, the passage ran suddenly into the main corridor. She passed the headland exit, and once more was on unknown ground. The passage swung round to the right and began to slope downhill. Jane held her candle high and looked at every step; but there were no more traps. She quickened her pace almost to a run as the dreadful thought came to her that Ember might follow Molloy. The passage sloped more and more. Finally there were steps, smooth, worn, and damp, that went down, and down, and down. At the bottom of the steps a yard or two of peculiarly slimy passage, and then a blank stone wall. Obviously Jane had arrived.

She looked at the stone wall, and the stone wall presented a front of uncompromising blankness. She looked up and she looked down, she looked to the left and she looked to the right, she gazed at the ceiling and she gazed at the floor. Nowhere was there any sign of a catch, a knob, a spring, or a lever. There must be one, but where was it? She tapped the wall and stamped on the floor, but with no result. The door in the panelling opened from inside with an ordinary handle. She had not been close enough to Lady Heritage to see what she did to pivot the stone behind the bench on the headland. In any case, this exit might have been quite differently planned.
