"I cannot--I cannot," cried Ezra feverishly. "I had to pay some money to Malton, and did so last week. There were some five-pound notes among that money, but I cannot tell where this particular one came from."

"Where did you get the money?" asked Naball.

"From the Hibernian Bank."

"Oh, but if you had to pay Malton money, why did you not do so by cheque?"

"Because I wanted some money myself, and did not care about drawing two cheques, so I drew one, covering what I owed to him and a little over."

"Humph!" Naball thought a moment. "You are sure of this?"

"Yes; it's the only way I can account for having the note. Whoever killed my father, must have paid it into the bank, and it came round to me by some fatality."

"Where were you on the night of the murder?"

"At the Bon-Bon Theatre."

"Afterwards?"
