"Now, sir," he said, "let us hear this problem."

The old man was not proof against the invitation.

"You shall, Richard," he exclaimed. "You are the very man to hear it.
Your aunt, Richard, is of too practical a mind for such speculations.
It's a most curious problem. Hubbard quite failed to throw any light upon
it. I myself am, I confess, bewildered. And I wonder if a fresh young
mind can help us to a solution." He patted his son on the shoulder and
then took him by the arm.

"The fresh young mind will have a go, father," said Dick. "Fire away."

"I was walking in the fields, my boy."

"Yes, sir, among the cows."

"Exactly, you put your finger on the very point. How is it, I asked

With outspread arms he asked for an answer and the answer came.

door Stella Ballantyne came out from her cottage to cross the meadow.
Dick was the first to hear the gate click as she unlatched it and passed
into the garden. He took a step towards the window, but his father
interposed and for once with a real authority.

"No, Richard," he said. "Wait with us here. Mrs. Ballantyne has something
to tell us."

"I thought so," said Dick quietly, and he came back to the other two men.
"Let me understand." His face was grave but without anger or any
confusion. "Stella returned here last night after I had taken her home?"

"Yes," said Thresk.

"To see you?"

"Yes."

"And my father came down and found you together?"

"Yes."

"I heard voices," Mr. Hazlewood hurriedly interposed, "and so naturally I
came down."

Dick turned to his father.

"That's all right, father. I didn't think you were listening at the
keyhole. I am not
