'If Rode murdered his wife, he had planned to do so long ago. The plastic cape, the boots, the weapon, the intricate timing, the use of Perkins to carry the case to your house—these are evidence of long premeditation. Of course one could ask: if that's so, why did he bother with Perkins at all—why didn't he keep the case with him all the time? But never mind. Let's see how he does it. He walks home with his wife after dinner, having deliberately forgotten the writing-case. Having left Stella at home, he returns to your house to collect it. It was a risky business, incidentally, leaving that case behind. Quite apart from the fact that one would expect him to have locked it, his wife might have noticed he hadn't got it as they left—or you might have noticed, or Miss Truebody—but luckily no one did. He collects the case, hurries back, kills her, fabricating the clues which mislead the police. He thrusts the cape, boots and gloves into the refugees' parcel, ties it up and prepares to make good his escape. He is alarmed by Mad Janie, perhaps, but reaches the lane and re-enters the house as Stanley Rode. Five minutes later he is with the D'Arcy's. From then on for the next forty-eight hours he is under constant supervision. Perhaps you didn't know this, Fielding, but the police found the murder weapon four miles down the road in a ditch. They found it within ten hours of the murder being discovered, long before Rode had a chance to throw it there.
'This is the point, though, Fielding. This is what they can't get over. I suppose it would be possible to make a phoney murder weapon. Rode could have taken hairs from Stella's comb, stuck them with human blood to a length of coaxial cable and planted the thing in a ditch
Then Smiley put his hand on Fielding's arm and said: 'Go now, in God's name go now. There's very little time, for Adrian's sake go now,' and Ailsa Brimley whispered something he could not hear.
Fielding seemed not to hear. His great head was thrown back, his eyes half closed, his wine glass still held between his thick fingers.
And the front-door bell rang out, like the scream of a woman in an empty house.
Smiley never knew what made the noise, whether it was Fielding's hands on the table as he stood up, or his chair, falling backwards. Perhaps it was not a noise at all, but simply the shock of violent movement when it was least expected; the sight of Fielding, who a moment before had sat lethargic in his chair, springing forward across the room. Then Rigby was holding him, had taken Fielding's right arm and done something to it so that Fielding cried out in pain and fear, swinging round to face them under the compulsion of Rigby's grip. Then Rigby was saying the words, and Fielding's terrified gaze fell upon Smiley.
'Stop him, stop him, Smiley, for God's sake! They'll hang me.' And he shouted the last two words again and again: 'Hang me, hang me,' until the detectives came in from the street, and shoved him without ceremony into a waiting car.
Smiley watched the car go. It didn't hurry, just picked its way down the wet street and disappeared. He remained there long after it had gone, looking towards the end of the road, so that passers-by stared oddly at him, or tried to follow his gaze. But there was nothing to see. Only the half-lit street, and the shadows moving along it.
