At the check-in, did the boxes go through the X-ray machine?' `No. The airport men just waved us through, past the queue.' And did you go straight on to the plane?'
`Yes. Mr Davey's man phoned from the car, and told them that we were coming.'
`Right, Mark,' said Skinner's voice from the tape machine. ‘I want you to think very carefully about this. During the flight, was anything said about the Red Boxes?'
`Yes. Just when April was taking me in to see Mr Shipley and Mr Garrett, in the cabin, I heard Mr Davey's man say to Victoria, "Miss Cunningham, I rather think we've got our boxes mixed up." Then the door closed, and I didn't hear any more. Not long after that..
Okay, Mark,' they heard Skinner say, quickly. 'We won't go into that.'
He switched off the tape and rewound the cassette.
`Wow,' said Sarah. 'Some kid.'
`What set you on the trail of Elliot?' asked Alex.
Skinner looked at her and shrugged. 'Luck. I was just starting to think, What if… but the thing that triggered it was Adam's mate Swift. The telly was on in the corner, without the sound, and he was watching it when he should have been listening to me. There was a by-election report on at the time, and they showed a picture of Leona, out canvassing, with Marsh Elliot by her side. Swift pointed at him. He said, "I know that bloke. He was my CO in the SBS and a right evil bastard he was too!" The whole room suddenly went as quiet as a tomb.
At first, we had worked on the assumption that someone had planted the bomb in Davey's box, while it was in Noble's keeping. Then when Andy's raid turned up the leather and the steel in Sawyer's workshop, we turned to the idea that he had made a dummy, and had got close enough to them somewhere to make a switch.'
He stood up, carefully, with Jazz sprawled across his left shoulder. 'But when Swift spotted Elliot, and said what he did, all of our thinking swung right around. What if… we all thought at once, and some of us said, ".. the bomb wasn't meant for Davey at all, but for Roland McGrath!" When Swift told us that Elliot had been a Marine before joining the SBS… as he'd told me earlier, and that his unit had been involved in mainland sabotage operations in the Falklands and elsewhere, the thing just took wings. I called the Secretary of State and asked him to check on all the Red Boxes in his Office, to see if they were all accounted for.'
`Why?' asked Alex, fascinated.
`Because the boxes are sometimes sent to constituencies with weekend work for the Ministers. And sometimes, there will be more than one box. Hardy often has three or four of the things at one go. He did the check and phoned me back to say that one of the Junior Ministers' boxes was missing.
At the same time, Adam Arrow was checking Elliot's military record. That's his report there.' He pointed to the document which Martin had read earlier. 'Summarised, it says that he was indeed in the SBS, but that he was removed from the active list after an operation in Africa, where he and his men were surprised by a family of civilians. Elliot ordered them killed — mother, father, grandmother and three children. His men refused to touch the children, so Elliot killed them himself.
After the operation, his young second-in-command.. Arrow's chum Swift… complained about the incident. There was an investigation. Elliot was retired, but the whole thing was covered up.
`Major Marshall Elliot is still in the Territorial Army, in the Artillery. Periodically, he goes on live firing exercises on the range in Northumberland. On the most recent session he attended, there was an unusually high incidence of faulty shells. Arrow is certain that they were faulty because Elliot removed their explosives. Apparently that's a trick his people used to pull in Ireland if they wanted to take care of someone in an untraceable way.'
`My God,' said Sarah. 'And this man became a political Agent.'
Bob raised an eyebrow. 'You don't think they vet them, do you? They'll take just about anyone who'll work for the money.'
`So you think that Elliot killed McGrath because…' Sarah began, until her husband interrupted, with a shake of his head.
`Not "think". We're bloody certain.'
Okay, whatever… killed him because McGrath had been having an affair with his wife?
And blew up the plane in the process.'
As for his motive, honking his wife would certainly be a main reason for Elliot deciding to kill him, but there was another. We know how zealous he was as a soldier, but according to Dame Janet Straw, he was just as big a fanatic as a Tory Agent. He was convinced that McGrath was going to lose the seat, and desperate about it. Finally, there was something else Dame Janet said to the Chief — that every Agent thinks he can do better than his MP.
Add them together: a cold-blooded killer, a politically driven fanatic and someone who believed that Roland McGrath was a loser. My guess is that Elliot is so unbalanced, that those three things alone would have tripped him into deciding to kill the man. Then sexual jealousy… which the Fiscal was ready to accept as Maurice Noble's motive… was added in. We've got Mark's clear evidence to vouch for that.'
He paused. 'But there's something else. Think back to the tape. According to Mark, Elliot said, "It's not just that you had her, but what you've done to her." Remember?'
`Yes,' said Alex. 'I wondered about that. What do you think he meant?'
Skinner glanced across at her. 'I hesitate to discuss this subject with my daughter, but it ties into something that Leona told Alison Higgins. About five years ago, Roly McGrath went on a swansong rugby tour of Europe with his old team. They were away for a couple of weeks, and when they got back, Roly brought Leona a nice wee present, just the thing for a chap to give his wife… genital herpes.'
Oh God,' said Sarah. 'That's awful. I've had patients whose lives have been ruined by that complaint. In terms of pain, incapacity and embarrassment, it's the worst sexually transmitted disease of them all. It's incurable, and when it flares up it's crippling for the patient. It's soul-destroying for a doctor, too. You feel so helpless in the face of your patient's suffering, because there's so little you can do. If Leona McGrath has that, she's marvellous to be doing what she is.'
Skinner nodded. 'Leona has it, and so has Margie Elliot. She admitted it to Brian Mackie this evening. Roly McGrath was generous enough to pass it on to her. That's how Marsh found out about them. When it broke out, she had to tell him.
`For all his other motives, I reckon that's why he decided to kill McGrath rather than just wait for him to lose Edinburgh Dean then stand for it himself at the first opportunity.'
He paused, letting his pronouncement sink in.
It isn't necessary to ask a jury to believe that he meant to cause the accident. Ministers don't work on their papers on public aircraft. He would expect that the box would travel safely to Edinburgh under McGrath's seat, and would have been opened later, either in the car that picked him up from the airport or back in the office.
And that's what would have happened, had he not switched the wrong box in the rush at Heathrow and had Maurice Noble not noticed it during the flight. But I reckon, even if he had considered the possibility, he'd still have gone through with it.'
Alex stepped up to him and lifted her brother from his cradling arms. 'Look, Pops,' she said quietly, breaking the enveloping silence which filled the room. 'I don't want to put a damper on things, but after all, I am a lawyer, even if I'm still wet behind the ears.
`Your whole evidential chain is predicated upon the word of a five-year-old, okay a remarkable one, but a five-year-old nonetheless, and one who has just survived the trauma of an air accident.
`Do you think you'll get him to perform in the witness box like he did for Uncle Bob, Uncle Andy and Auntie Maggie? And even if you do, that defence Counsel will not be able to plant a reasonable doubt in the mind of the jury? You won't be allowed to lead evidence of Elliot's SBS atrocity, you know.'
