She turned with them without a word. She had failed miserably. The upholders of law and order had scored signally over the scattered and imperfect organisation of the brotherhood. Between them, she walked through the long, brilliantly-lit rooms. The Chief of Police tucked her arm under his, keeping a tight hold on her wrist. The other five men accompanied them. There was nothing in the general attitude to suggest that she was not a very charming woman being escorted by a bevy of admirers. Contraras was standing by the door as the procession passed out. Agitated as she was, she saw him, and flashed at him an agonised glance. He flashed back at her a glance equally eloquent. He knew the Chief of Police by sight, and he understood what had happened. Poor little Valerie had failed! They would take her to some room, and search her. In her pocket they would find those cunning little bombs that, once launched, would have sent tyrants and oppressors hurling into space, and proclaimed the dawn of the new era. Poor little Valerie! His eyes grew misty. As she had failed, it would have been better if he had left her alone. If ever he felt remorse in his life, he felt it that night. His first impulse was to leave the Palace at once. But wiser thoughts prevailed. The Chief of Police had recognised him, he was sure. If he left immediately, it might give cause for suspicion. Valerie had failed. For the moment the Cause had suffered a set-back. But his resolution was still undaunted, his brain still active. Because he had failed to-day, it did not follow that he would not be successful to-morrow. He sought out the Duchess del Pineda, who was, as usual, surrounded by a group of chattering friends. "Good evening, Duchess. What has become of our young friend, Mademoiselle Delmonte?" "I really cannot tell you. She broke away from me a long time ago. She has been a tremendous success, I can assure you. I hope she intends to make a long stay in Madrid. She will be most popular." "I really cannot tell you. I know nothing of her plans," answered Contraras in his grave, quiet tones. "As I told the Duke, I met her in France and England, where she appeared to move in the best circles." "Naturally," said the innocent Duchess. Nobody would suspect the highly respected Contraras of telling a deliberate lie. Outside the Palace, the crowd had thinned, but Moreno and Violet Hargrave still waited. Midnight had struck and all was quiet. There were no signs that heralded the happening of a tragedy. A few belated arrivals passed through to the Palace. The crowd began to melt away. And then there was a little stir. A carriage drove up outside the Palace doors. Two men and a woman stepped into it, the woman was in evening dress. The carriage passed the two watchers. Mrs Hargrave peered into the slowly-moving vehicle.
