"That's to be found out, and I'm going to, as little Gracie says. If he has given me something to ponder over I've given him something that'll set his wits at work, unless I'm very much mistaken; and I haven't half done with him, nor a quarter. Don't ask me what my plans are; it would be the spoiling of them if I let you into the secret--and I mustn't forget that an inspector of police is in the room, who would do his duty though it should break the hearts of those who are dearest to him." These words were spoken with exceeding tenderness, and caused more than one heart in the room to throb. "If cunning is to be met with cunning, watching with watching, spying with spying, trickery with trickery, Dr. Vinsen will find that I am ready for him. Look here. What makes him start up all at once and go to Mrs. Death, and on the very first night he sees her give her a couple of sovereigns? Benevolence? Charity? That for his benevolence and charity!" Dick snapped his fingers contemptuously. "What makes him tell Mrs. Death a parcel of lies to poison her ears against me? What makes him tell me at your father's funeral, Reginald, that his heart is large, that it bleeds for all, and that it would be better for some of us if we were in our graves? What do I care for his bleeding heart, the infernal hypocrite? I'd make it bleed if I had my will of him, with his fringe of hair round his shining bald head! As for Dr. Pye, that mysterious gentleman keeps himself in the background till he sends a letter to the Coroner, saying he has evidence of great importance to give. We heard what that evidence was, and we've a lot to thank him for, haven't we? Did you notice him as he looked round the court till he stopped at Reginald? Accident? No! Premeditation!" They started. "I repeat--premeditation. I don't know for what reason, but I _will_ know. I don't know what tie there is between Dr. Pye and Dr. Vinsen, but I _will_ know. There's black treachery somewhere, and I'll ferret it out. Uncle, Aunt, Florence, Reginald, don't think I'm mad. I give you my word I am in my sober senses when I say that behind the mystery of this dreadful murder that has brought so much sorrow into this happy home there is another mystery which I'm going to solve if I die for it! I'll leave no stone unturned--for your dear sakes!" His earnestness, his sincerity, the fervour of his voice, the loving glances he cast upon them, sank into their hearts--but it was upon Florence's face that his gaze lingered, and he trembled when, murmuring, "Dear Dick, you fill us with hope!" she gave him a sisterly kiss. "Dick," said Aunt Rob, tearfully, "there was a time when I thought you had no stability, and when I said as much to Uncle Rob. I take it back, my lad, I take it back!"
