"May I inquire who knew of this watching of yours?" asked Mary Ursula, her tone full of resentment.

"Not any one, madam. Not any one in the world."

"Not Mr. Harry Castlemaine?"

"Oh, no. I should not dare to speak of the subject to him, unless he first spoke of it to me. I have wished he would."

"As there is nothing more that can be done here to-night, of watching or else, I think you had better return home, Jane Hallet," spoke Miss Castlemaine in the same proud, cold tone: though she inwardly wondered which way of egress Jane would take.

"I was just going," spoke the trembling girl. "There--there is not--oh! forgive me, madam!--any one lying wounded on the beach, I hope?"

"I presume not," replied Miss Castlemaine. "The superintendent and his men are there."

Jane Hallet turned meekly, and disappeared amid the pillars. Miss Castlemaine rightly conjectured that there must be some stairs leading from these lower cloisters to the cloisters above that opened on the chapel ruins. By these Jane had no doubt descended, and would now ascend. In point of fact, it was so. George Hallet had eventually made a clean breast of all the secret to Jane, including the openings and passages. But the underground passage to the Grey Nunnery neither he nor any one else had known of.

Miss Castlemaine turned to it now. She was crossing towards it, her dim lantern held aloft to steer her between the pillars, when her foot stumbled against something. Pacing slowly, she did not fall, and recovered herself at once. Bringing the light to bear, she stooped down and saw a man lying there on his back. He looked immensely tall, and wore a big cape, and had a cap muffled over his forehead and eyes, and lay still as one dead. With another faint sickness of heart, Mary pulled the cap upwards, for she thought she recognised the handsome features. Alas, yes! they were those of Harry Castlemaine: and they were set in what looked like the rigidness of death.

With a shrill cry--for her feelings got the better of her--Mary called him by name, and shook him gently. No, there was no response: he was surely dead! She tore the cape and cap off, flinging them aside; she put her hand to his heart, and could feel no pulse; she lifted one of his hands, and it fell again like a heavy weight. There could be little doubt that he must have been wounded during the fight, had run into the vaults, intending to make his escape by the chapel ruins, and had fallen down exhausted. Panting with fear and emotion, all considerations lost sight of in this one great shock, Mary went back to the beach crying for aid, and supremely astonishing Mr. Superintendent Nettleby.
