“He did?”

Mrs. Lock’s face flushed, and Nick did not ask her to tell him how Redway knew it.

He took Redway’s pistol from his pocket, and showed it to her.

“Is your pistol like this?”

“It is a duplicate. Victor bought the two at the same time. Mine has his initials on it, and his has mine.”

“Then he thought there would be no danger of the bullet and his pistol not corresponding,” smiled Nick.

“Who could the disguised assassin have been?”

“Can’t you guess?”

“I guess? Why, who do I know—surely not——”

“Yes. Oscar Gay.”
