When they met again at breakfast , the girl stepped up to her aunt and kissed her on both cheeks -- an unusual greeting . She was her bright self again ; talked merrily ; read aloud a letter from her father , which proved that at the time of writing he had not seen Arnold Jacks . `` I must write to the Doctor to-morrow , '' she said , with an air of reflection . At ten o'clock they drove to the station . While Miss Derwent took her ticket Mrs. Hannaford walked on the platform . On issuing from the booking-office , Irene saw her aunt in conversation with a man , who , in the same moment , turned abruptly and walked away . Neither she nor her aunt spoke of this incident , but Irene noticed that the other was a little flushed .
