“I am trying to,” I said. “And now I must consult Mademoiselle Elven. Will you help me?”

“What can I do?” she asked, piteously.

“Stand by that window. Look, madame, can you see the lights on the semaphore?”

“Yes.”

“Count them aloud.”

She counted the white lights for me, then the red ones.

“Now,” I said, “if those lights change in number or color or position, come instantly to me. I shall be with Mademoiselle Elven in the little tea-room. But,” I added, “I do not expect any change in the lights; it is only a precaution.”

I left her in the shadow of the curtains, and passed through the room to Sylvia’s side. She looked up quietly from her embroidery frame, then, dropping the tinted silks and needles on the cloth, rose and walked beside me past Eyre, who stood up as we came abreast of him.

Sylvia paused. “Monsieur Eyre,” she said, “I have a question to ask you ... some day,” and passed on with a smile and a slight inclination of her head, leaving Eyre looking after her with heavy eyes.

When we entered the little tea-room she passed on to the lounge and seated herself on the padded arm; I turned, closed the door, and walked straight toward her.
