"Because I thought that here, at least, you would have sense enough to see them. In Biskra it was impossible to argue with you. You made your own arrangements against my wishes. I left it, feeling convinced that the impossibility of it would be brought home to you here, and that you would see for yourself that it was out of the question. Diana, give up this insane trip."

"I will not."

"I've a thundering good mind to make you."

"You can't. I'm my own mistress. You have no right over me at all. You have no claim on me. You haven't even that of ordinary brotherly affection, for you have never given me any, so you cannot expect it from me. We needn't make any pretence about it, I am not going to argue any more. I will not go back to Biskra."

"If you are afraid of being laughed at——" he sneered; but she took him up swiftly.

"I am not afraid of being laughed at. Only cowards are afraid of that, and I am not a coward."

"Diana, listen to reason!"

"Aubrey! I have said my last word. Nothing will alter my determination to go on this trip. Your arguments do not convince me, who know you. It is your own considerations and not mine that are at the bottom of your remonstrances. You do not deny it, because you can't, because it is true."

They were facing each other across the little table. An angry flush rose in Sir Aubrey's face, and his eyeglass fell with a little sharp tinkle against a waistcoat button.

"You're a damned obstinate little devil!" he said furiously.
