“Have you any idea where the medallions were usually kept?” he inquired.
Cecil went over to one of the shelves and searched rapidly.
“Why, there are only two of them here!” he exclaimed in dismay.
“Hush!” Sir Clinton warned him sharply. “Don’t make a row. Have a good look at the things.”
Cecil picked up the medallions and scanned them minutely. His face showed his amazement as he turned from one to another.
“These are the replicas! Where have the genuine Leonardos gone?”
“Never mind that for the present. Put these things back again. I’m going to close the safe. We mustn’t risk talking too much here; and the sooner we’re gone the better.”
He picked up the otophone and led the way out of the museum.
“You might bring Froggatt back to his post here,” he said. “We don’t need him at the stair any longer. I must go upstairs again for a moment with this machine.”
Cecil piloted Froggatt back to his original post just as the Chief Constable rejoined them.
