The door was opened by Miss Coburn herself. It happened that the sun was shining directly in her eyes, and she could not therefore see her visitors’ features.

“You are the gentlemen who wished to see Mr. Coburn, I presume?” she said before Merriman could speak. “He is at the works. You will find him in his office.”

Merriman stepped forward, his cap off.

“Don’t you remember me, Miss Coburn?” he said earnestly. “I had the pleasure of meeting you in May, when you were so kind as to give me petrol to get me to Bordeaux.”

Miss Coburn looked at him more carefully, and her manner, which had up to then been polite, but coolly self-contained, suddenly changed. Her face grew dead white and she put her hand sharply to her side, as though to check the rapid beating of her heart. For a moment she seemed unable to speak, then, recovering herself with a visible effort, she answered in a voice that trembled in spite of herself:

“Mr. Merriman, isn’t it? Of course I remember. Won’t you come in? My father will be back directly.”

She was rapidly regaining self-control, and by the time Merriman had presented Hilliard her manner had become almost normal. She led the way to a comfortably furnished sitting-room looking out over the river.

“Hilliard and I are on a motor launch tour across France,” Merriman went on. “He worked from England down the coast to Bordeaux, where I joined him, and we hope eventually to cross the country to the Mediterranean and do the Riviera from the sea.”

“How perfectly delightful,” Miss Coburn replied. “I envy you.”

“Yes, it’s very jolly doing these rivers and canals,” Hilliard interposed. “I have spent two or three holidays that way now, and it has always been worth while.”
