Aileen was chagrined.

Her voice showed it.

They had been scheduled to go to dinner with the Hoecksemas, and afterward to the theater.

Cowperwood suggested that she should go alone, but Aileen declined rather sharply; she hung up the receiver without even the pretense of a good-by.

And then at ten o'clock he telephoned again, saying that he had changed his mind, and that if she were interested to go anywhere--a later supper, or the like--she should dress, otherwise he would come home expecting to remain.
Aileen immediately concluded that some scheme he had had to amuse himself had fallen through.
