"Wait a moment," said Norwood. "If Sir Rupert did not know of the existence of this secret place, he can hardly have hidden anything in it." May Penfold's face fell. "No--that's true," she replied dismally, "however, I will show it to you, and then we will find some means to open these other drawers.' "The end of this will be a search-warrant," said Dowker decisively. May did not reply; but leaning on the desk, pressed her fingers on the ears of the Shakespeare head--a sharp click was heard--and she lifted out the whole face of the carving, disclosing a wide place, but with no depth, so that any articles placed therein would have to stand on end. As she removed the carving Dowker gave an exclamation and bent forward, for there before them was an old-fashioned locket, a slender gold chain, and an arrow-head. The three looked at one another in silence, which was broken by Dowker. "This," he said, taking up the locket, "is without doubt what you allude to, Miss Penfold--see, there is a fair curl and a dark curl of hair on this side, and on the other the face of a man--or rather a boy." And indeed the face looked like that of a boy--smooth face--black hair--clearly-cut features and dark eyes. "Who can it be?" said May, gazing at it. "I've seen that face before." "So have I," answered Dowker with decision, "there is something in it familiar; but is this the locket you have seen Lady Balscombe wear?" "Yes--and this is the chain." "So far, so good," said Norwood, taking up the arrow-head, "but what is this?" Dowker looked at it for a moment, and then smiled. "I would advise you to take care of that," he said quietly, "it's poisoned." "Poisoned!" echoed Norwood, and quickly replaced it in the drawer, "how do you know?" "Because I am certain that it is the weapon with which the crime was committed--we were misled by the Malay kriss, but this is a certainty." "Then you think Sir Rupert guilty?" asked May in dismay. "Sir Rupert is jealous of his wife--he follows her on that night, knowing she is going to elope--meets her in Piccadilly, and is seen following her by one witness--is overheard having angry words with her by a second, who also sees him wrench a locket off her neck--his wife is found dead--and in a secret drawer, known only to Sir Rupert, yourself, and the dead woman, is found the locket and the weapon with which the crime was committed. I think the case is clear enough." "What will you do now?" asked Norwood. "Put them back for the present," said Dowker, replacing the locket and chain, "and wait here for Sir Rupert. I will question him. He will deny it. Then I will confound him by showing him the evidence of his guilt. Will you kindly replace the carving, Miss Penfold." May did as she was told in silence, for though this discovery would save her lover, yet she was deeply grieved at the thought of what it meant to her guardian. "If his wife had been a good woman this would not have happened," she said bitterly.
