"A copy of this photograph taken at the prison of Barcelona, is in every detective office in Spain," was his reply. "Rodriquez Despujol is the most dangerous and elusive criminal at large," he went on. "He never leaves anything to chance. No doubt he believed that you were in possession of something valuable, and his intention was to drug you and get it. But you were too quick for him. My chief surprise is why, when he found himself cornered as he was, that he did not draw his knife and attack you." "But I had a pistol!" I said. "Despujol does not fear pistols. Before you could pull the trigger he could have pounced upon you like a cat!" replied the police official. "Well, he certainly entirely misled me," I exclaimed. "I even offered him an apology for my attitude towards him." The three men laughed heartily. "An apology to Despujol!" cried the Chief of Police. "How very amusing!" "I consider that I was very lucky," I said. "He seems to be a most desperate character." "He is," answered Señor Andrade. "We have had inquiries for him from all over Europe. During the war it seems that he served as a spy of Germany in France, hence the military authorities there are very anxious to get him." "But you think he lives in France and crosses the frontier every now and then." "Yes. We received information to that effect about a year ago. He probably lives as a poor, but perfectly honest man in one of the remote villages in the Pyrenees, and is perhaps held in high esteem by all around him. It was the case of the notorious Maurice Tricoche who escaped us for years and lived near Luchon until he was betrayed by a woman whose husband he had maltreated. Perhaps Despujol will also be betrayed. We hope so!" "I cannot understand why the fellow dared to put foot into Madrid when he knows how active we are in search of him," remarked Señor Rivero, turning to me. "He must have followed you with evil intent. The explanation of mistaking your room was, of course, a good one, but entirely false." I longed to tell the police all about the mystery of Stretton Street, and the grave suspicions concerning the great international financier who was at that moment at the Ritz. Yet I hesitated for two reasons, the first being that I feared lest my story should be disbelieved, and secondly, because I had, on behalf of the beautiful girl with whom I had fallen in love, set out to solve the enigma by myself, and bring the culprit to justice. "If Despujol is arrested I will willingly come forward and give evidence--that is, if I am still in Spain," I promised. But both police officials shrugged their shoulders, and the detective remarked: "Despujol is a will o' the wisp. There seems little hope of our ever securing him. Nevertheless we shall continue to do our best to allow you to face him again one day. And then, señor, you will realize what a miraculous escape you have had!"
