Captain Kynaston took the favourable opportunity of escaping across the hall, where he spent the remainder of the evening, dividing his attention between the music and supper rooms, and Helen saw him no more that night.

She saw, however, some one she had not reckoned upon seeing.  Glancing carelessly across to the end of the room, she perceived, talking to Lady Kynaston, a little French gentleman, with a smooth black head, a neat, pointed, little black beard, and the red ribbon of the Legion d’Honneur in his button-hole.

What there was in the sight of so harmless and inoffensive a personage to upset her it may be difficult to say; but the fact is that, when Mrs. Romer perceived this polite little Frenchman talking to her hostess, she turned suddenly so sick and white, that a lady sitting near her asked her if she was going to faint.

“I feel it a little hot,” she murmured; “I think I will go into the next room.”  She rose and attempted to escape—­whether from the heat or the observation of the little Frenchman was best known to herself.

Her maneuver, however, was not destined to succeed.  Before she could work her way half-way through the crush to the door, the man whom she was bent upon avoiding turned round and saw her.  A look of glad recognition flashed into his face, and he instantly left Lady Kynaston’s side, and came across the room to speak to her.

“This is an unlooked-for pleasure, madame.”

“I certainly never expected to meet you here, Monsieur D’Arblet,” faltered Helen, turning red and white alternately.

“Will you not come and have a little conversation with me?”

“I was just going away.”

“So soon!  Oh, bien! then I will take you to your carriage.”  He held out his arm, and Helen was perforce obliged to take it.

There was a little delay in the hall, whilst Helen waited for her, or rather for her grandfather’s carriage, during which she stood with her hand upon her unwelcome friend’s arm.  Whilst they were waiting he whispered something eagerly in her ear.

“No, no; it is impossible!” reiterated Helen, with much apparent distress.

Monsieur D’Arblet whispered something more.

“Very well, if you insist upon it!” she said, faintly, and then got into her carriage and was driven away.

Before, however, she had left Walpole Lodge five minutes, she called out to the servants to stop the carriage.  The footman descended from the box and came round to the window.

They had drawn up by the side of a long wall quite beyond the crowd of carriages that was waiting at Lady Kynaston’s house.

“I want to wait here a few minutes, for—­for a gentleman I am going to drive back to town,” she said to the servant, confusedly.  She was ashamed to give such an order to him.

She was frightened too, and trembled with nervousness lest any one should see her waiting here.
