A minute later he went by in the moonlight, waving his hand to her as she stood silhouetted on the terrace above him.  Then, to her annoyance, the motor stopped and he leaped out.  For a moment her heart stood still in alarm, for if he was coming back the work might be to do all over again.  He did come back, scrambling up the steps till he was at her feet.  But it was only to seize her hand and kiss it hastily, after which, without a word, he was off again.  Then once more the huge machine clattered and whizzed and throbbed, rattling its way down the drive and on into the dark, till all sound died away in the solemn winter silence.

During the next half-hour small practical tasks occupied Diane’s mind and kept the thought of Derek Pruyn’s arrival from becoming more than a subconscious dread.  She informed the manager of her success with his mysterious young guest, and arranged that Dorothea, when she came, should spend the night with her.  Then she put herself in telephonic communication, first with Mrs. Wappinger, and then with Fulton.  She gave the former the intelligence that Carli had departed, and received from the latter the information that Simmons had found his master, who had been able to leave for Lakefield by the ten-five train.  These steps being taken, there was nothing to do but to sit down and wait for Dorothea.  Allowing thirty or forty minutes for possible delays, she calculated that the girl ought to arrive a good half-hour before her father.  This would give her time to deal with each separately, clearing up misunderstandings on both sides, and preparing the way for such a meeting as would lead to mutual concessions and future peace.

Physically tired, she took off her hat and threw herself on the couch in her little sitting-room.  By sheer force of will she continued to shut out Derek from her thought, concentrating all her mental faculties on the arguments and persuasions she should bring to bear on Dorothea.  She had no nervousness on this account.  The naughty, headstrong child that runs away from home does not get far without a realizing sense of its happy shelter.  She divined that the long ride through the dark, with an unknown man, toward an unknown goal, would have already subdued Dorothea’s spirits to the point where she would be only too glad to find herself dropping into familiar, feminine arms.

At eleven o’clock she got up from her couch with a vague impulse to be in a more direct attitude of welcome.  At half-past eleven she went to the office to inquire of the manager how long a motor going slowly should take to reach Lakefield from New York, assuming that it had got away from the city about six o’clock.  Alarmed by his reply, she begged him to keep a certain number of the servants up, and the hotel in readiness to cope with any emergency or accident, promising liberal remuneration for all unusual work.  After that came another long hour
