Dr. Lytton’s arm reached toward his friend.

“We’ve come here to listen, not to argue,” he cautioned.

“Pardon me,” De Medici sighed. His face resumed its mask of calm and interest.

“Certainly,” Norton answered. “I’m sorry to go into this. But there’s nothing to be gained now by not facing the facts.”

“Quite right,” Dr. Lytton smiled. “The facts are what we want.”

“The facts are that Mr. Ballau more than anyone else desired the match,” De Medici spoke.

“Or seemed to,” Norton interrupted. “But on the night that the engagement was to have been announced he quite changed his mind about the desirability of the match. And he played his trump card with the girl. It was Ballau who telephoned her at the theater at half-past nine. This was a very easy fact to establish. The telephone girl of the Hudson Apartments remembered distinctly, and we have no reason to doubt her word, that Mr. Ballau asked her to get his daughter on the phone at the Galt Theater. Her memorandum pad of outgoing calls contains the notation, ‘Ballau—Columbus 2600. 9:28.’”

“Are you certain,” Dr. Lytton interrupted, “that the notation refers to an outgoing call? It may have been Miss Ballau who telephoned her father.”

“No,” Norton shook his head. “There are three items of evidence bearing on the point. One is the testimony of the telephone girl. Another is the fact that Cort, the stage manager, summoned Miss Ballau to the phone, and the third is the memorandum pad itself. The call appears listed in the column marked ‘Outgoing.’”

Norton leaned back in his chair, his face grown serious and aloof.
