Carlton. She was jealous now. That was why she had been so angry with
Garstin. That was why she had lain awake that night.

And yet the next morning she had gone to the studio in Glebe Place. She
had greeted Arabian as usual. She had never let him know that she had
seen him in the restaurant, and she had persuaded Dick Garstin to say
nothing about it. No doubt Arabian supposed that he had been too quick
for them, and that they did not know he was with the woman who had come
in and had almost immediately gone out.

But since that night Miss Van Tuyn had been persecuted by a secret
jealousy such as she had never known till now.

Let him sink back to the depths! She had said that, but she did not
want him to disappear out of her life. She had said, too, that he
was horrible. The words were spoken in a moment of intense nervous
irritation. But were they true? She thought of him as a night bird. Yet
she brought him to Claridge's and introduced him to Fanny, and sought
Fanny's opinion of him, and been pleased that it was favourable. And
she saw him almost daily. And she knew she would go on seeing him
till--what?

She could not foresee the end of this adventure brought about by her
own audacious wilfulness. Some day she supposed Dick Garstin would be
satisfied with his work. A successful portrait of Arabian would stand on
the easel in Glebe Place. Garstin was not at all satisfied yet. She knew
that. He had put aside two more beginnings angrily, had started again,
had paused, taken up other work, taken a rest, sent for Arabian once
more. But this strange impotence of Garstin to satisfy himself would
surely not last for ever. Either he would succeed, or he would abandon
the attempt to succeed, or--a third possibility presented itself to Miss
Van Tuyn's mind--his model would get tired of the conflict and refuse to
"sit" any more.

And then--the depths?

Till now Arabian's patience had been remarkable. Evidently Garstin's
obstinacy was matched by an obstinacy in him. Although he had once
perhaps been secretly reluctant to sit, had been tempted to become
Garstin's model by the promise of the finished picture, he now
seemed determined to do his part, endured Garstin's irritability,
dissatisfaction, abandoned and renewed attempts to "make a first-rate
job of him" with remarkable good temper. He was evidently resolved not
to give up this enterprise without his reward. There was fixed purpose
in his patience.
