"I fancy so," Abell replied thoughtfully. "You are interested in the Ravenspur case?"
A lurid light leapt into the Russian's eyes. He seemed to be strangely moved. He paced up and down the room, dragging his maimed limb after him.
"Never more interested in anything in my life," he said. "You know as much of my past as any man, but there are matters, experiences unspeakable. My face, my ruined frame! Whence come these cruel misfortunes? That secret will go down with me to the grave. Of that I could speak to one man alone, and I know not whether that man is alive or dead."
Tchigorsky's words trailed off into a rambling incoherent murmur. He was far away with his own gloomy and painful thoughts. Then he came back to earth with a start. He stood with his back to the fireplace, contemplating Abell.
"I am deeply interested in the Ravenspur case, as you know," he said. "A malignant fiend is at work yonder--a fiend with knowledge absolutely supernatural. You smile! I myself have seen the powers of darkness doing the bidding of mortal man. All the detectives in Europe will never lay hands upon the destroyer of the Ravenspurs. And yet, in certain circumstances, I could."
"Then, in that case, sir, why don't you?"
"Do it? I said in certain circumstances. I have part of a devilish puzzle; the other part is in the hands of a man who may be dead. I hold half of the bank-note; somebody else has the other moiety. Until we can come together, we are both paupers. If I can find that other man, and he has the nerve and the pluck he used to possess, the curse of the Ravenspurs will cease. But, then, I shall never see my friend again."
"Impossible. That man and myself made a most hazardous expedition in search of dreadful knowledge. That formula we found. For the purposes of safety, we divided it. And then we were discovered. Of what followed I dare not speak. I dare not even think.
"I escaped from my dire peril, but I cannot hope that my comrade was so fortunate. He must be dead. And, without him, I am as powerless as if I knew nothing. I have no proof. Yet I know quite well who is responsible for those murders at Ravenspur."
Abell stared at his chief in astonishment. He knew Tchigorsky too well to doubt the evidence of his simple word. The Russian was too strong a man to boast.
