"Exactly!"
Naball scribbled a line or two in his pocket-book, and shut it with a snap.
"If that note goes into circulation," he said, in a satisfied tone, "I'll soon trace it to its original holder."
"And then?" asked Ezra.
"And then," reiterated Naball quietly, "I'll lay my hands on the man who killed your father. And now, Mr. Stewart, I want to ask you a few questions about yourself."
"Go on!" said Keith imperturbably; "I hope you don't think I killed Lazarus?"
"I think--nothing," replied Naball quietly; "I only want to find out as much as I can. You were at the Bon-Bon Theatre on that night?"
"Yes; talking to Mr. Mortimer."
"Any one else with you?"
"Yes," replied Ezra, "I was, and Caprice; we left about half-past eleven."
