“It is not necessary,” she answered. “Mr. Macheson does not count. You can say whatever you will before him.”

A smile that was half a sneer curved his lips. He was like a rat in a corner, and he knew that he must fight. He must use the weapon which he had feared with a coward’s fear.

“The matter on which I wish to speak to you,” he said, looking straight at her, “is not directly connected with the affair which we have been discussing. If you will give me two minutes, I think I can make you understand.”

She met his challenge without flinching. She was a shade paler, perhaps; the little glow which the walk through the enchanted twilight had brought into her cheeks had faded away. But her gaze was as cool and contemptuous as before. She showed no sign of any fear—of any desire to conciliate.

“I think,” she said, “that I can understand without. You can consider that we are alone. Whatever you may have to say to me, I should prefer that Mr. Macheson also heard.”

Macheson looked from one to the other uneasily.

“Shall I wait in the passage?” he asked. “I should be within call.”

“Certainly not,” she answered. “This person,” she continued, indicating Stephen with a scornful gesture, “is, I believe, about to make a bungling attempt to blackmail me! I should much prefer that you were present.”

Stephen Hurd drew a sharp breath. Her words stung like whips.

“I don’t know—about blackmail,” he said, still holding himself in. “I want nothing from you. I only ask to be left alone. Stop this nonsense about Letty Foulton and let me catch my train. That’s all I want.”
