The Hindu returned a few minutes later.

"Man to see you, sahib."

"What's his name, Abdul?"

"Mr. Isaac Coffran."

Duncan fairly leaped from his chair.

"Bring him in, Abdul," he exclaimed.

The visitor was the man to whom the last letter had been addressed!

The Hindu ushered an elderly gentleman into the room. The newcomer was of slight build and stoop-shouldered. He used a cane as he walked, and he turned his head upward to stare at Duncan with sharp, blue eyes that were both friendly and inquisitive.

He accepted Bruce Duncan's handshake and sat in the armchair facing the fireplace, while the young man took a position close beside him.

A strange old fellow, thought Duncan. Older than his uncle, yet alert despite his age. It was impossible to determine the exact age of Isaac Coffran. The man's face was clean-shaven, and his cheeks were smooth and tight.
