Yet even then she did not guess what Ruthven Smith's plan was until the thing had happened. He peered at the brooch, which represented a bunch of grapes in small cabochon amethysts and leaves of green enamel. Adjusting his eyeglasses, they slipped from his nose and fell on the lace of her fichu.

"Oh, how awkward of me! A thousand pardons!" he cried. Making a nervous grab for the glasses, which hung from a chain, he snatched up her chain as well, and with a quick jerk of seeming inadvertence wrenched from its warm hiding-place a ring with a flash of brilliants and a glint of blue.

Annesley's heart had given one great throb and then missed a beat, for there had been an awful instant as the "plan" developed when she feared that the ring with the blue diamond might, after all her pains, have become entangled with the chain. If it had, the violence of the jerk might have brought it to light.

But she had accomplished her task well. She could afford to smile, though her lips trembled, as she saw the bird-of-prey look fade from Ruthven Smith's face and turn into bewildered humiliation.

Right was on his side; yet he had the air of a culprit, and some wild strain in Annesley's nature which had been asleep till that instant sang a song of triumph in the victory of her "plan" over his. How delighted Knight would be, and how amazed and grateful—grateful as he had been when she "stood by him" with the watchers!

As Ruthven Smith stammered apologies her eyes flashed to Knight's; but there was none of the defiant laughter she had expected, and felt bound to reproach him for later.

He was pale, and though his immense power of self-control kept him in check, Annesley shrank almost with horror from the fury of rage against Ruthven Smith which she read in her husband's gaze and the beating of the veins in his temples.

Terrified lest his anger should break out in words, she hurried on to say what she would have said before the sudden move by the jewel expert.

"Here is the sapphire ring you asked about, Knight," she said. "I was just going to take off this chain and give it to you to show to the Duke when——"

"When Mr. Ruthven Smith took an unwarrantable liberty," Knight finished the sentence icily.
