“Yes, sir.”

“Do you know them?” Nick inquired, turning to Mrs. Darling.

“Hardly more than by name,” she replied. “My husband introduced me to one of them, named Philip Floyd, who has called several times to see him. I have met the other only once.”

“What is his name?” asked Nick, proceeding to write them in his notebook.

“Ralph Sheldon. He called here a few days ago with Mr. Floyd, who introduced me to him. My husband was absent at the time and they remained only a few minutes. That is the only time I ever saw Mr. Sheldon, though my husband had frequently mentioned him.”

“Are they old friends of his?”

“Quite the contrary. I never heard of them until about a month ago.”

“Had they any business relations with your husband?”

“I cannot say.”

“Do you know anything about them?”
