"Why, sir, you've got me the very evidence I want," said the inspector warmly, shaking my friend by the hand. "I was on the same scent as you from the first." "What! You were after Henderson?" "Why, Mr. Holmes, when you were crawling in the shrubbery at High Gable I was up one of the trees in the plantation and saw you down below. It was just who would get his evidence first." "Then why did you arrest the mulatto?" Baynes chuckled. "I was sure Henderson, as he calls himself, felt that he was suspected, and that he would lie low and make no move so long as he thought he was in any danger. I arrested the wrong man to make him believe that our eyes were off him. I knew he would be likely to clear off then and give us a chance of getting at Miss Burnet." Holmes laid his hand upon the inspector's shoulder. "You will rise high in your profession. You have instinct and intuition," said he. Baynes flushed with pleasure. "I've had a plain-clothes man waiting at the station all the week. Wherever the High Gable folk go he will keep them in sight. But he must have been hard put to it when Miss Burnet broke away. However, your man picked her up, and it all ends well. We can't arrest without her evidence, that is clear, so the sooner we get a statement the better." "Every minute she gets stronger," said Holmes, glancing at the governess. "But tell me, Baynes, who is this man Henderson?" "Henderson," the inspector answered, "is Don Murillo, once called the Tiger of San Pedro." The Tiger of San Pedro! The whole history of the man came back to me in a flash. He had made his name as the most lewd and bloodthirsty tyrant that had ever governed any country with a pretence to civilization. Strong, fearless, and energetic, he had sufficient virtue to enable him to impose his odious vices upon a cowering people for ten or twelve years. His name was a terror through all Central America. At the end of that time there was a universal rising against him. But he was as cunning as he was cruel, and at the first whisper of coming trouble he had secretly conveyed his treasures aboard a ship which was manned by devoted adherents. It was an empty palace which was stormed by the insurgents next day. The dictator, his two children, his secretary, and his wealth had all escaped them. From that moment he had vanished from the world, and his identity had been a frequent subject for comment in the European press. "Yes, sir, Don Murillo, the Tiger of San Pedro," said Baynes. "If you look it up you will find that the San Pedro colours are green and white, same as in the note, Mr. Holmes. Henderson he called himself, but I traced him back, Paris and Rome and Madrid to Barcelona, where his ship came in in '86. They've been looking for him all the time for their revenge, but it is only now that they have begun to find him out."
