“You need not worry,” said the stranger to Hugh. “I am not your enemy, but a friend. I warn you that Marseilles is unsafe for you. Get away as soon as possible. The Spanish police have learnt that you have come here,” he went on as he strolled at his side.

Hugh was amazed.

“How did you know my identity?” he asked eagerly.

“I was instructed to watch for your arrival—and to warn you.”

“Who instructed you?”

“A friend of yours—and mine—The Sparrow.”

“Has he been here?”

“No. He spoke to me on the telephone from Paris.”

“What were his instructions?”

“That you were to go at once—to-night—by car to the Hotel de Paris, at Cette. A car and driver awaits you at the Garage Beauvau, in the Rue Beauvau. I have arranged everything at The Sparrow’s orders. You are one of Us, I understand,” and the man laughed lightly.
