Rathbone smiled bleakly. “I have no intention of offering you one, Lord Cardew. I totally agree with you. And believe me, if it is I who stand in court before a judge and jury to plead Rupert’s case, I will draw such a portrait of Mickey Parfitt that they will see him for what he was. But I will need more than his depravity to justify his death. The jury will require to know why Rupert in particular, of all his victims, was the one who actually killed him. I must tell it from his point of view, in particulars, not generalities. They must walk in his shoes, feel his fear, outrage, whatever it was that drove him to such an act. The prosecutor will be clever and articulate also, and will defend Parfitt’s right to live as he would that of any of us.”

“Of course. I understand. We cannot allow any one of us to be the unappointed judge and executioner of another. The simple answer is that I don’t know why Rupert killed him. I didn’t have the chance to ask him. And to tell you the truth, I am not sure whether he would tell me …” He struggled for a moment to find words for what he could hardly bear to say.

Rathbone put an end to it, as one would put an animal out of its pain. “Of course,” he said, cutting across him, “it is often easier to speak to someone whose opinion does not touch your emotions. It happens to many of the people I see in my office. With your permission, I shall go to the prison and speak to Rupert immediately.” He rose to his feet. “I think we should address this as soon as possible. I will see that he is being reasonably treated, and that he has all that he is permitted for his comfort. I will speak to you as soon as I have something of value to say.” He held out his hand.

Cardew rose to his feet slowly. It seemed to cost him some effort, but when he clasped Rathbone’s hand, it was with surprising power. A drowning man, reaching for help amid the overwhelming waves.

BY EARLY AFTERNOON RATHBONE was in the entrance of Newgate Prison. The huge iron doors closed behind him, and a sour-faced warden beckoned him along the narrow corridors toward the cell where he would be permitted to interview Rupert Cardew. His footsteps sounded hard on the floor, but the echo died almost immediately, as if the stone of the walls suffocated it. The place was a curious mixture of life and death. Rathbone was acutely conscious of emotional pain, of fear, remorse, the dread of physical extinction and what might lie beyond in the nightmares of the soul. And yet the place stifled life. There was no energy, nothing could breathe here, nothing could grow or have will.
