"It interested me extremely."
"You are aware that we hold Mr. Stanniford's permission to open the door on the twenty-first birthday of his son?"
"I remember."
"The twenty-first birthday is to-day."
"Have you opened it?" I asked eagerly.
"Not yet, sir," said he gravely. "I have reason to believe that it would be well to have witnesses present when that door is opened. You are a lawyer, and you are acquainted with the facts. Will you be present on the occasion?"
"Most certainly."
"You are employed during the day, and so am I. Shall we meet at nine o'clock at the house?"
"I will come with pleasure."
"Then you will find us waiting for you. Good-bye, for the present." He bowed solemnly, and took his leave.
