Detective-Inspector Herrion was a forceful man, and he had set himself the task of finding Sir Raife, the missing baronet, and he had determined to run Malsano to earth. On the day when he had let Lesigne slip through his fingers at Raife's flat in the Rue Lafayette, Herrion had a suspicion that he had been tricked by the innocent-looking old lady, who appeared to be so busy dusting out the apartment. The flat of Monsieur Henri Vachelle was, therefore, kept under observation, but Malsano was far too wily a criminal to be trapped easily, and the flat was deserted, and the gang found fresh quarters. Herrion was sitting in his room at the obscure little hotel that he affected, when the telephone bell rang, and, removing the receiver, he took a message to the effect that, if he would call at the prefecture, there was important news awaiting him. Hastily seizing his cap he started off. He was met at the entrance by a sergeant, who said: "Quick, Mr Herrion, I think we have found your missing `Baron.' Will you come with me to the Avenue des Champs Elysees?" A taxi was in waiting, and they entered together. As the car sped towards the famous avenue, the sergeant told Herrion: "We have received a letter, an anonymous letter, saying that a burglary will be committed to-night. The house is surrounded, and it is believed that it is the gang of that old scoundrel, Malsano. The gang is in force, and the cunning old reprobate has chosen the house of the Lady Remington, who is the wife of your missing `Baron.'" Herrion was agitated, a weakness the astute detective-inspector seldom allowed himself to indulge in. With a smile of satisfaction the little man remarked: "If that man Malsano is in this affair, for heaven's sake don't let him escape. It looks as if we are in for a breezy time. I have no power here, and I can only look on. Mind, the men of Malsano's gang do not hesitate to shoot. Shoot on the least suspicion. Shoot first, not to kill, only to maim." The gendarme looked at Herrion, raising his eyebrows as he said: "Monsieur Herrion, we shall not be unprepared, and we are not so tender with our criminals as you gentlemen across the Channel. We, too, have a score to settle with this Malsano. And there is that mysterious woman, who seems to be all over Europe at the same time. I have seen her. Ma foi! She is clever and beautiful, too." Herrion replied: "Yes, that is the woman who is responsible for Sir Raife Remington's downfall. She is dangerous, but she is the decoy and the tool of that doctor fellow Malsano." The taxi stopped at a corner of a street, and they alighted. Seven or eight men were secreted in doorways, and the sergeant approached each one separately and gave them whispered instructions. Herrion's position was quite unofficial, but his popularity with the police of Paris had made it possible for him to be present and to participate in the "round-up," or coup.
