At last the time had come. Nina made her way, with much difficulty, to the witness-box; steadily took her stand and was sworn. All Kimberley, as she knew, was looking intently and watching her every gesture. She had changed greatly in the last few weeks, and now looked, for her, thin and worn—almost ill. The usual warmth of her dark beauty was lacking. An ivory pallor overspread her face; but her glorious eyes were firm, open and determined, and honesty and truth, men well might see, were in her glance. She looked once quickly at the two judges and the magistrate sitting with them, and then her eyes met Frank’s, and for him a world of sympathy was in them. It did Frank good and he breathed more freely. Nina, at all events, was the Nina of old.

The prosecuting advocate opened the girl’s evidence quietly, with the usual preliminaries. Then very gently he asked Nina if she was well acquainted with the prisoner. Her reply was, “Yes, very well acquainted.”

“I suppose,” continued counsel, “I may even call him a friend of yours?”

“Yes,” replied Nina, “a very great friend.”

“Without penetrating unduly into your private affairs and sympathies, Miss Staarbrucker,” went on the advocate, “I will ask you to tell the court shortly what you actually saw on the night in question—the night, I mean, when the diamond was first seen by yourself and your brother.”

Here was Nina’s opportunity, and she took advantage of it. She told plainly, yet graphically, the story of that evening; she portrayed the amazed delight of Frank on the discovery of the stone, his free avowal of his find, the knife in his hand, the open crocodile on the table, the pebbles previously taken from the reptile’s stomach. She went on with her story with only such pauses as the taking of the judge’s notes required. Counsel, once or twice, attempted to pull her up; she was going much too fast and too far to please him; but the court allowed her to complete her narrative. She dealt with the next two days. Mr Farnborough had kept the diamond, it was true. He was puzzled to know what to do with it. He had, finally, announced his intention of giving it up and declaring it, and he would undoubtedly have done so, but for his arrest. The stone might have been stolen, or it might not, but Mr Farnborough, as all his friends knew, was absolutely incapable of stealing diamonds, or of buying diamonds, knowing them to be stolen. The stone came into his possession in a perfectly innocent manner, as she could and did testify on oath. As for her brother’s suspicions, she could not answer for or understand them. For two days, he at all events had had none; she could not account for his sudden change. Spite of the judge’s cautions, she concluded a breathless little harangue—for she had let herself go completely now—by expressing her emphatic belief in Frank’s absolute innocence.

She had finished, and in her now deathly pale beauty was leaving the box. There were no further questions asked by counsel upon either side. Nina had said far too much for the one, and the advocate for the defence judged it wiser to leave such a runaway severely alone. Who knew in what direction she might turn next? He whispered regretfully to his solicitor: “If we had got hold of that girl, by George! we might have done some good with her—with a martingale and double bit on.”

The senior judge, as Nina concluded, remarked blandly—for he had an eye for beauty—“I am afraid we have allowed you a good deal too much latitude. Miss Staarbrucker, and a great deal of what you have told the court is quite inadmissible as evidence.”

As for Otto, he had stared with open mouth and fixed glare at his sister during her brief episode. He now heaved a deep breath of relief, as he watched the judges.

“Thank God!” he said to himself savagely under his breath, “she has overdone it, and spoilt her own game—the little fool!”
