"Look!" he cried. "See! There is a little piece of a different wood let in here--round like a large wooden stud! I wonder what it is?" He pressed it with his fingers, but to no avail. Therefore he took out his pocket-knife and with the end pressed down hard, throwing all his weight upon his hand. "It gives!" he cried excitedly. "There's some spring behind it! You are stronger," he exclaimed, turning to the younger man. "Try. Push down, so!" CHAPTER THIRTY TWO. THE TICKING OF THE CLOCK. The man with the grey hat took the pocket-knife, knelt over the spot, placed the knife in position, and pressed with all his might, when slowly a panel of the oak wainscoting about two feet square fell forward until it lay flat at right angles, disclosing a small locked door behind. "This is it, no doubt!" cried the doctor, tugging at the door. It yielded, disclosing a secret cupboard. A clock set upon a cabinet on the side of the room near where I was hidden was ticking. I had not noticed that sound before, and I thought it strange. Miller held the candle while the others peered within. They all had their backs turned to me, and in my eagerness I bent forward in order to obtain a better view of what was concealed there. "See!" cried Gavazzi. "I was not mistaken! I knew he had some secret hiding-place here. In this room he spent days, sometimes with me, but more often locked in here alone. Fortunately for us, the police know nothing of this." "Yes," exclaimed Miller. "Let us see what his treasures are. I wonder what he would say if he saw us handling his secrets," he added, with a short dry laugh. "The papers to-day say that he's been seen in Bahia." Evidently Lucie had for some reason kept her knowledge of the fugitive's death from her father. "He was always methodical," remarked the Italian. "And he seems to have carried out his methods here. Look at all these pigeon-holes! Made by himself, it seems, from their roughness. He dared not call in a carpenter. But he was of a very mechanical turn of mind, and probably constructed the whole thing himself." "It certainly would escape observation," remarked the young man, examining the thick old panel of polished oak that had fallen back. The doctor had drawn from one of the pigeon-holes a bundle of official-looking papers folded and secured with tape. He glanced at them with critical eye and cast them aside as being without interest. Another, and another, he drew out, but none of them attracted his attention for more than a few moments. "They are merely secret information collected against various politicians and personages--information that he thought might one day be useful," said Gavazzi. "And profitable, eh?" added Miller, with a laugh. "Quite so. We may find it equally profitable to us one day," remarked his companion. "They will prove interesting reading when we have time to go through them."
