"Surely you don't wish me to believe my pretty Sofia has turned thief?"

That stung her pride. She drew upon an unsuspected store of spirit,
confronting him bravely.

"What is it to me, what you choose to think?"

"I refuse to think that of you. My reason will not let me believe it."

She saw that he was shaking with rage; so she shrugged and drawled: "Oh,
your _reason_--!"

"It tells me you for one did not come here to-night uninvited." He was
rapidly losing grip on his temper. "Oh, it's plain enough! I was a fool not
to understand, there in the auction room, when my face was slapped with
proof of your liaison with this Lanyard!"

She said in mild expostulation: "But you are quite mad."

"Perhaps--but not so as to be blind to the truth. You had him there this
afternoon to bid that picture in for you if your own means failed. Why else
should the man, who knows pictures as I know you, pay twenty thousand
guineas for a footling copy of a Corot that wouldn't deceive a--a Royal
Academician! Yes: he bid it in for you--the sorry fool!--bought with his
own money the evidence of your infatuation for his predecessor in your
affections--and expects you here to-night to receive it from him and--pay
him _his_ price! Ah, don't try to deny it!"

He growled like a very animal, beside himself. "Why else should you be
admitted to these rooms without question in his absence?"
