"My dear Mrs. Prendergast," expostulated the doctor mildly, "your note--I saw it in the regular way of business--said 'merely a cold;' and Wilmot and I both know you always say what you mean--no more and no less."

Henrietta smiled rather grimly as she replied, "I must say, you are adroit in turning a slight into a compliment. And now we will talk about my cold."

They did talk about her cold, and Dr. Whittaker duly prescribed for it, emphatically forbidding exposure to the weather. Just as he rose to take leave, Henrietta asked him what sort of spirits Wilmot appeared to be in.

"Very low indeed," said Dr. Whittaker; "but I think the change of air will do him good."

The change was likely to be sufficiently profitable to Dr. Whittaker to make it only natural that he should regard it with warm approbation, without reflecting very severely upon his sincerity either; he was but human, and not particularly prosperous.

"What change?" asked Henrietta in a tone which had not all the indifference which she had desired to lend it. (Dr. Whittaker had seen and guessed enough to make it just that he should not look for much warmth from Mabel's friend in speaking of Mabel's husband; and Mrs. Prendergast never overlooked the relative positions in any situation.)

"What! don't you know, then? He is going abroad--going to Paris, and then to Berlin, partly to recruit, and partly to inquire into some new theory about fever they've got there. I don't generally think much of their theories myself, especially in Berlin."

But Dr. Whittaker's opinions had no interest for Henrietta. His news occupied her. She did not altogether like this move. She did not believe in either of the reasons assigned; she felt certain there was something behind them both, and that that something had been in Wilmot's mind when she last saw him. What was it? Was he flying from a memory or a presence? If the former, then something more than she was in possession of had come to his knowledge concerning Mabel; for much as he had been shocked, and intensely as he had felt all she had told him, Henrietta knew Wilmot too well to believe for a moment that the present resolution was to be traced to that source. If the latter, the presence must be that of Miss Kilsyth; and there must be dangers in her way, complications in this matter, she did not understand, some grave error in her calculation. True, he might be flying away in despair; but that could hardly be. In so short an interval of time it was impossible he could have dared or even tried his fate. It was the unexpectedness of this occurrence that gave it so much power to trouble Henrietta. She had made a careful calculation; but this was outside it, and it puzzled her. She took leave of Dr. Whittaker, while these and many more equally distracting thoughts passed through her mind, in a sufficiently absent manner, and listened to his expression of a sanguine hope of finding her much better on the morrow through a sedulous observance of his advice, with as much indifference as though he had been talking about somebody else's cold. When he had left her, she sat still for a while; then put on her warmest attire, sent for a cab, and, utterly regardless of Dr. Whittaker's prohibition, drove straight to Mrs. Charlton's house in South-street, Park-lane.

Mrs. Prendergast's cab drew up behind a carriage which had just stopped before Mrs. Charlton's door, at that moment opened in reply to the defiant summons of the footman, who was none other than one of the ambrosial Mercuries in attendance on Lady Muriel Kilsyth. An elderly lady, rather oddly dressed, descended from the equipage, bestowed a familiar nod upon its remaining occupant from the steps, and walked into the house. Mrs. Prendergast was then admitted; and as the carriage which made way for her was displaced, she recognised in the face of the lady who sat in it Lady Muriel Kilsyth.

"That is very odd," she thought; "I wonder who she has set down here, and why she has not come in herself."
