Great was the distress and the perplexity which the lovers felt while consulting together and determining what was to be done in such an emergency. They could not endure the thought of a separation. They could not be married to each other, for Somerset was married already. For Lady Neville to remain single all her life in order to be at liberty to indulge a guilty passion was an idea not to be entertained. They knew, too, that their present relations to each other could not long be continued. A thousand circumstances might happen at any time to interrupt or to terminate it, and it could not be long, in any event, before it must come to an end. So it was agreed between them that Lady Neville should accede to the great minister's proposal and become his wife. In the mean time, until the period should arrive for the consummation of the marriage, they were to renew and redouble their intimacy with each other, taking, however, every possible precaution to conceal their movements from the eyes of others. So the duke's offer was accepted, and it was soon made known to all the court that Lady Neville was his affianced bride. [Sidenote: The duke becomes uneasy.] Thus far Lady Neville had treated the duke with great reserve in her accidental intercourse with him at the reunions of the court, but now, since he was her accepted lover, he thought he might reasonably expect a greater degree of cordiality in her demeanor toward him. But he found no change. She continued as formal and reserved as ever. Moreover, when he went to visit her, which he did sometimes several times a day, she was very often not at home--much too often, he thought. He went to the place where her domestics said she had gone in such cases, but she was very seldom to be found. He soon came to the conclusion that there was some strange mystery involved in the affair, and he determined to adopt effectual measures for unraveling it. [Sidenote: His spies.] So he employed certain trusty persons who were in his service to watch and see where Lady Neville went, and how she passed her time during these unaccountable absences from home. For many days this watch was continued, but no discoveries were made. The spies reported that they could not keep upon the lady's track. In spite of their best exertions she would contrive to elude them, and for several hours every day they lost sight of her altogether. They saw enough, however, to satisfy them that there was something wrong going on. What it was, however, they could not discover, so shrewd and complete were the precautions which Somerset and Lady Neville had taken to prevent detection.
