The door closed on the last word. Elsie heard the high, rather strident voices of the women calling salute and impatience; then Masterson's reply set in a key of strained merriment. The motor roared under the chauffeur's hand. They were departing; evidently a means of inflating the tire had been found.

The peace of Elsie's day had departed with them. The alteration in Masterson frightened her; the strangeness of his manner and of his invitation filled her with anxiety. Something was wrong; something she could not guess or understand. Why should he have spoken so of Holly? Why, too, did he want Anthony this night?

Was Mrs. Masterson to be one of the party at the restaurant? That idea came later. The mere possibility of such an event fixed Elsie's decision; she would not send Anthony to the meeting desired. She would let Masterson's accidental visit pass unnoticed.

But when evening came, and with it Adriance, ruddy with the March wind, boyishly hungry and gay; when he took his wife in his arms and kissed her with the deep tenderness that the morning had added to their first love, Elsie knew better. Better any misfortune than the barrier of deceit between them. And she remembered in time that it was not for her to deprive him of his right of decision and free-will.

She waited until supper was eaten and the blue-and-white dishes shining in their rack again beside the ten-cent-shop china.

"Shall we go on with our book?" Adriance proposed, when his pipe was lit. Now that the moment had come, it pleased him to dally with the surprise he held for her, to prolong his secret content. He stretched luxuriously in his arm-chair. "Lord, it's good to get home! Funny I never cared much about books until we took to reading aloud, isn't it? Come over and settle down. I think we'll turn in early to-night, if you don't mind, girl. I want to do some extra work, to-morrow."

She came to him rather slowly.

"Mr. Masterson was here to-day," she said reluctantly. "He came by chance, to borrow something for his automobile. I think it was a tire-pump. Of course he was surprised to find me. And he left this for you."

Astonished, he took the card, pulling her down beside him; and they read the message together. It was very brief, yet somehow carried a force of compulsion. Masterson urged his friend to go that night to the ball-room of a certain restaurant known to every New Yorker, and there wait until he, Masterson, joined him.

There was a pause after the reading. Adriance stared at the card with the knitted brow of perplexity, while Elsie watched his face in tense suspense.
