And now they were in Silwood's room, which was still known as Silwood's, though it knew Silwood no more. It was changed, however, but little since he had sat in it and worked his wicked will. "Close the door, Gilbert," said Eversleigh. The son obeyed, and then glanced about him. He could see no sign of disturbance, nothing that indicated specially the burglary of which his father had given a suggestion on the stairs. There were in the room, as of yore, the same table, chair, book-cases, deed-boxes; all were arranged in the way that was familiar enough to him. The large japanned box stood by itself in the usual corner. There appeared to be absolutely no hint of anything out of the ordinary. This rapid scrutiny over, Gilbert looked at his father inquiringly. "You don't notice anything particularly?" asked Eversleigh. "No; that is, at a superficial glance." "I wish you to examine the bottom of that box," said Eversleigh, pointing to the large japanned box in the corner. "You and Mr. Archer Martin have recently had constant access to it for the purpose of going over Mr. Silwood's books and papers; you therefore know it well. Now you will see something I am sure you know nothing of. I did not know of it myself--not until Whittaker showed me it." While Eversleigh was speaking, his son was looking at the foot of the box, from which he saw there protruded a narrow strip of metal. "What do you make of _that_?" asked the father, huskily. "I should say it was a sort of secret chamber--you can't exactly call it a drawer," Gilbert replied, after a study of the box. "I knew nothing of it; you are right there. How has it been discovered? What was found in it?" he inquired eagerly, while other questions came thronging into his mind. "When was this discovery made?" he went on. "It was made this morning," replied Eversleigh. "Whittaker tells me he had occasion to come into the room a few minutes ago to get a paper which he thought he'd find here. He could not lay his hand on it quickly, and had to hunt for it. Quite by accident, as he was searching, he happened to observe a strip of metal at the foot of the box sticking out. Naturally, he went and examined the box, and then saw the secret chamber, which he declares was empty, and I don't doubt it. Now he is positive that when he saw the box yesterday this secret chamber was closed." "Positive! In what way?" "It seems that he and one of the other clerks required to move the box yesterday. And he maintains that one or other of them, or both, must have seen the secret chamber if it had been open then. He concludes, of course, that it has been opened since he saw it last. His theory is that it was opened last night by a burglar. I don't know whether he really believes that; it appears preposterous and beyond possibility that any ordinary burglar would be acquainted with this secret chamber."
