'No, it isn't. At this moment all three of them are travelling from Norwich in Angelo's car.' I told him the make, the colour, the number, and that it had a bashed-in nearside rear wing. 'They are probably going to Harry Gilbert's house in Welwyn Garden City. I think Angelo also lives there, but perhaps not Eddy.' I gave him the address. 'They should arrive there in about an hour and a quarter to an hour and a half. In the car there is a Walther. 22 pistol with a silencer. There may or may not be bullets in it. It may or may not be the pistol which Angelo waved at me, but it looks identical. It might be the pistol which killed Christopher Norwood.'
'That's very useful, sir,' Robson said,
'There's one more thing…'
'Yes?'
'I don't think Harry Gilbert knows anything at all about Chris Norwood's death. I mean, I don't think he even knows he's dead. If you go to arrest Angelo, Harry Gilbert won't know why.'
'Thank you, sir.'
That's all,' I said.
'Er,' he said,'the Chief Superintendent will be in touch with you.'
'All right, but-' I hesitated.
'Yes, sir?'
'I'd be glad to know…'
'Just a minute, sir,' he interrupted, and kept me hanging on through some lengthy unintelligible background talk. 'Sorry, sir, you were saying?'
'You remember I sent Angelo some computer tapes with games on?'
'Yes, I do. We went to Cambridge main post office and alerted the man whose job it was to hand out letters-to-be-called-for, but unfortunately he went for his tea-break without mentioning it to anyone, and during that short period your package was collected. A girl clerk handed it over. We didn't find out until it was too late, It was… infuriating.'
'Mm,' I said. 'Well, Angelo came back with more threats, demanding the real tapes, and I've just given them to him. Only…'
'Only what, sir?'
'Only they won't be able to run them on their computer. I think when they get home they might try those tapes straight away, and when they find they don't work they might… well they might set out to look for me. I mean-'
'I know exactly what you mean,' he said dryly.
'So, er, I'd be glad to know if you plan to do anything about Angelo this evening. And if you think there's enough to hold him on.'
'Instructions have already gone off,' he said. 'He'll be picked up tonight as soon as he reaches the house in Welwyn. We have some fingerprints to match… and some girls who saw two men arrive at Norwood 's. So don't worry, once we've got him, we won't let him go.'
'Could I ring up to find out?'
'Yes.' He gave me a new number. 'Call there. I'll leave a message. You'll get it straight away.'
'Thank you,' I said gratefully,'very much.'
'Mr Derry?'
'Yes?'
'What's wrong with the tapes this time?'
'Oh, I stuck magnets into the cases.'
He laughed. 'I'll see you later, perhaps,' he said. 'And thanks. Thanks a lot.'
I put the receiver down smiling, thinking of the three powerful Magnadur magnets distorting the programs on the tapes. The permanent magnets which were black and flat; two inches long, three-quarters of an inch wide, three-sixteeenths of an inch thick. I'd stuck one into the inside of each case, flat on the bottom, black as the plastic, looking like part of the case itself. I'd taken the tapes and the cases separately to Harry Gilbert's- the tapes in the one pocket, the cases in another- and only after he'd played them had I married them all together. Sandwiching electro-magnetic recording tapes between such magnets was like wiping a blackboard roughly with a wet sponge: there would be traces of what had been recorded there, but not enough to make sense.
It might take Angelo all the way home to see what I'd done, because the magnets did look as if they belonged there.
Or it might not.
I drove wearily in the direction of home. I seemed to have been driving for ever. It had been a very long day. Extraordinary to think it was only that morning that I'd set out from Ted Pitts's.
Both of the girls went to sleep as the miles unrolled, the deep sleep of release and exhaustion. I wondered briefly what would become of us in the future, but mostly I just thought about driving and keeping my own eyelids apart.
We stayed in a motel on the outskirts of London and slept as if dead. The alarm call I'd asked for dragged me from limbo at seven in the morning and, yawning like a great white shark, I got through to the number Inspector Robson had given me.
'Jonathan Derry,' I said. 'Am I too early?'
It was a girl's voice which answered, fresh and unofficial. 'No, it's not too early,' she said. 'John Robson asked me to tell you that Angelo Gilbert and his cousin Eddy are in custody.'
'Thank you very much.'
'Any time.'
I put the receiver down with a steadily lightening heart and shook Sarah awake in the next bed.
'Sorry,' I said, 'but I've got to be in school by nine o'clock.'
