They then all repaired to the laboratory together, where the Earl made Dr. Lascelles acquainted, in a hasty whisper, with the cause of Mrs. Bunce's appearance on the stage of their present proceedings.

The moment the woman emerged from the darkness of the landing outside to the light of the laboratory, she cast a hasty and inquiring glance around on those present; but her eyes settled on Jacob Smith, and she was evidently much astonished to see him dressed in a plain but most respectable manner, and looking neat, clean, and even interesting in his appearance. For the lad possessed good features—very bright eyes—and a set of white, even teeth; and though his countenance was still somewhat indicative of a sickly constitution, it nevertheless showed a state of health considerably improved by the excitement of travelling and by the happiness imparted to his soul by the successful escape of Thomas Rainford.

Jacob saw that Mrs. Bunce surveyed him with interest; and at the moment he felt pity for the woman who had on many occasions shown him some kindness, and towards whom he had also experienced at times unaccountable heart-yearnings;—but he could not blame himself for having just now entrapped her into the power of Lord Ellingham, because he knew how important it was to assemble in the presence of that nobleman as many of Old Death's accomplices as possible. Besides, he was well aware that no harm was intended her; and this assurance he conveyed to her in a hasty whisper—though not in such a way as to induce her to believe that he was any longer an accomplice also.

"You will now accompany me below," said the Earl, addressing himself to his three servants.

Jacob hastened to light another lamp (of which there were several in the laboratory); and the Earl, attended by his domestics, proceeded into the adjoining bed-room, whence they passed down into the subterranean.

Dr. Lascelles, Mrs. Bunce, and Jacob were left together in the laboratory.

"What does all this mean?" demanded the woman, accosting the lad in an imploring manner—for she was afraid, in spite of the whispered assurance she had received from him.

"I cannot give you any explanation," answered Jacob aloud. "But I may go so far as to promise you—and this good gentleman," he added, turning towards the doctor, "will confirm my words—that no harm is intended to you, provided you give faithful replies to the questions that will be put to you presently."

"The lad speaks quite properly, woman," said the physician; "and you had better hold your tongue until the prisoners make their appearance."

"The prisoners!" muttered Mrs. Bunce; and it struck her that allusion must be made to Old Death and Tidmarsh.
