"Any fresh development of the case?" asked Ezra.
"Yes," said Naball solemnly. "I received this note to-day, and traced it back to Malton; he says it was given to him by you."
Ezra examined the note with great interest, and on turning it over saw the fatal words endorsed. He looked up quickly to Naball.
"This is one of the notes that were stolen?" he asked.
"Yes," replied Naball; "and Malton said it was given to him by you."
"By me!" repeated Ezra in amazement. "How on earth could I come across this note?"
"That's what I want to find out," said Naball.
Ezra looked at him for a moment, then the whole situation seemed to burst on him, and with a stifled groan the unhappy young man fell back into his chair, burying his face in his hands.
"Good God!" he cried, "you don't suspect me of killing my father?"
"If you are innocent, you can explain where you got the note."
