She had done--unwittingly--an awful and terrible thing--the very worst crime, in her eyes, that woman ever committed--she saw it in all its horror.

Her very blindness in not having guessed her husband's secret seemed now to her another deadly sin.

She ought to have known! she ought to have known! How could she imagine that a man who could love with so much intensity as Percy Blakeney had loved her from the first--how could such a man be the brainless idiot he chose to appear?
She, at least, ought to have known that he was wearing a mask, and having found that out, she should have torn it from his face, whenever they were alone together.
Her love for him had been paltry and weak, easily crushed by her own pride; and she, too, had worn a mask in assuming a contempt for him, whilst, as a matter of fact, she completely misunderstood him.
But there was no time now to go over the past.

By her own blindness she had sinned; now she must repay, not by empty remorse, but by prompt and useful action.
Percy had started for Calais, utterly unconscious of the fact that his most relentless enemy was on his heels.

He had set sail early that morning from London Bridge.
