“Sure. That old farmer, Montagu, told me of seeing Miss Porter drop something in the well yesterday; but I haven’t had time to examine the well today.”

Thorne rose and, walking over to the table in the window, pulled open its drawer. “Here’s the cut,” he announced, taking out a square piece of metal caked with mud. “Montagu also told me, and I searched the well this afternoon with his aid.”

Mitchell took the cut and gingerly turned it over. “So Dorothy Deane told the truth,” he muttered, “and got ‘fired’ for it.” And as Thorne glanced up in surprise he briefly recounted the scene in the newspaper office. At its conclusion he rose. “I’m glad to have had this talk with you, doctor.”

“Cato,” he called, removing his coat, “Cato!”
