"Keep calm, my boy," urged the doctor; "it can profit us nothing, it can profit Myra nothing, for you to shatter your nerves at a time when real trials are before you. You are inviting another breakdown. Oh! I know it is hard; but for everybody's sake try to keep yourself in hand."

"I am trying, sir," replied Robert hollowly.

Dr. Cairn nodded, drumming his fingers upon his knee.

"We must be diplomatic," he continued. "That James Saunderson proposed to return to London, I had no idea. I thought that Myra would be far outside the Black maelström in Scotland. Had I suspected that Saunderson would come to London, I should have made other arrangements."

"Of course, sir, I know that. But even so we could never have foreseen this."

Dr. Cairn shook his head.

"To think that whilst we have been scouring Egypt from Port Said to Assouan—he has been laughing at us in London!" he said. "Directly after the affair at Méydûm he must have left the country—how, Heaven only knows. That letter is three weeks old, now?"

Robert Cairn nodded. "What may have happened since—what may have happened!"

"You take too gloomy a view. James Saunderson is a Roman guardian. Even Antony Ferrara could make little headway there."

"But Myra says that—Ferrara is—a frequent visitor."
