The medical man who was sent for to attend the sick woman discovered at once that she was suffering from a serious affection of the heart.  The illness lasted long, left her very weak, and returned at intervals, though with mitigated severity, again and again.  They remained at Grimsby, in consequence, during the first half of the new year, and there they might probably have stayed much longer, but for the sudden resolution which Anne took at this time to venture back to Hampshire, for the purpose of obtaining a private interview with Lady Glyde.

Mrs. Clements did all in her power to oppose the execution of this hazardous and unaccountable project.  No explanation of her motives was offered by Anne, except that she believed the day of her death was not far off, and that she had something on her mind which must be communicated to Lady Glyde, at any risk, in secret.  Her resolution to accomplish this purpose was so firmly settled that she declared her intention of going to Hampshire by herself if Mrs. Clements felt any unwillingness to go with her.  The doctor, on being consulted, was of opinion that serious opposition to her wishes would, in all probability, produce another and perhaps a fatal fit of illness, and Mrs. Clements, under this advice, yielded to necessity, and once more, with sad forebodings of trouble and danger to come, allowed Anne Catherick to have her own way.

On the journey from London to Hampshire Mrs. Clements discovered that one of their fellow-passengers was well acquainted with the neighbourhood of Blackwater, and could give her all the information she needed on the subject of localities.  In this way she found out that the only place they could go to, which was not dangerously near to Sir Percival’s residence, was a large village called Sandon.  The distance here from Blackwater Park was between three and four miles—­and that distance, and back again, Anne had walked on each occasion when she had appeared in the neighbourhood of the lake.

For the few days during which they were at Sandon without being discovered they had lived a little away from the village, in the cottage of a decent widow-woman who had a bedroom to let, and whose discreet silence Mrs. Clements had done her best to secure, for the first week at least.  She had also tried hard to induce Anne to be content with writing to Lady Glyde, in the first instance; but the failure of the warning contained in the anonymous letter sent to Limmeridge had made Anne resolute to speak this time, and obstinate in the determination to go on her errand alone.

Mrs. Clements, nevertheless, followed her privately on each occasion when she went to the lake, without, however, venturing near enough to the boat-house to be witness of what took place there.  When Anne returned for the last time from the dangerous neighbourhood, the fatigue of walking, day after day, distances which were far too great for her strength, added to the exhausting effect of the agitation from which she had suffered, produced the result which Mrs. Clements had dreaded all along.  The old pain over the heart and the other symptoms of the illness at Grimsby returned, and Anne was confined to her bed in the cottage.
