The man addressed muttered something in an undertone, and, turning, gazed abstractedly out of the window.

They were in Hugh’s sitting-room in St. James’s on the morning fixed for the marriage. It was almost a month since Trethowen had left Spa, and the time had been pleasantly spent with Valérie at Brussels and Ostend. Now that they had returned to London, she had again taken up her abode in her little flat in Victoria Street, while the arrangements for the marriage were completed.

Jack Egerton, dressed more sprucely than usual, and wearing the orthodox lavender gloves and a flower in his coat, had called upon his friend half an hour before, and was waiting to accompany him to the church. His task he regarded with abhorrence. He would rather have done anything than assist at the ceremony, and see his friend bind himself to that dark-eyed Circe. Yet he, helpless and under the merciless thrall of the woman, was there by sheer compulsion. A fortnight ago he had received a letter from her. She did not ask or entreat, but commanded him to be present and act as Hugh’s best man.

“I know,” she wrote in French, “the task will be scarcely congenial, but your presence will inspire him with confidence. He has promised me he will ask you, and if you refuse, he will suspect that it is repugnant to you. Understand, he must know nothing of my affairs. When we last met at Laroche you threatened me, but I need hardly impress the necessity of silence upon you, having regard to the fact that the reward of your zealousness on your friend’s behalf would be a life sentence. Accept his offer and attend the wedding, otherwise I shall know you are playing against me. If you do, beware! for I shall win. I have all the honours in my hand.”

He was reflecting upon this last sentence as he stood staring aimlessly down into the street. She possessed the dark secret of his life, and held him in her power, so that he was compelled to do her bidding, to dance attendance upon her, and to witness her triumph at the expense of his dearest friend.

Grinding his teeth, he uttered an imprecation, as he realised how complete was her mastery, and perceived that his own ruin would be the only reward for saving Hugh.

The latter, who was watching him, misconstrued this outburst of impatience and went over and grasped his hand, saying:

“Forgive me, old fellow, for what I’ve just said. We ought not to quarrel, more especially to-day. I was rather hasty, but I love Valérie, and anything hinted against her excites my anger. Come, let’s forget it.” His companion succumbed to fate, having done all he could in the way of resistance. Laughing a trifle sadly, he replied—

“There’s nothing whatever to forgive. I shall go with you to the church, and I hope—well, I hope your marriage will bring you nothing but happiness. Nevertheless, whatever is the result, remember I am still your friend.”

Trethowen thanked him, although astonished at his friend’s tone, and inwardly tried to account for his apparent sadness.
