Read this extract from The Destructors, and then answer the question that follows it: On Sunday morning all were punctual except Blackie, even Mike. Mike had had a stroke of luck. His mother felt ill, his father was tired after Saturday night, and he was told to go to church alone with many warnings of what would happen if he strayed. Blackie had had difficulty in smuggling out the saw, and then in finding the sledge-hammer at the back of number 15. He approached the house from a lane at the rear of the garden, for fear of the policeman's beat along the main road. The tired evergreens kept off a stormy sun: another wet Bank Holiday was being prepared over the Atlantic, beginning in swirls of dust under the trees. Blackie climbed the wall into Misery's garden. There was no sign of anybody anywhere. The loo stood like a tomb in a neglected graveyard. The curtains were drawn. The house slept. Blackie lumbered nearer with the saw and the sledge-hammer. Perhaps after all nobody had turned up: the plan had been a wild invention: they had woken wiser. But when he came close to the back door he could hear a confusion of sound, hardly louder than a hive in swarm: a clickety-clack, a bang bang bang, a scraping, a creaking, a sudden painful crack. He thought, It's true, and whistled. They opened the back door to him and he came in. He had at once the impression of organisation, very different from the old happy-go-lucky ways under his leadership. For a while he wandered up and down stairs looking for T. Nobody addressed him: he had a sense of great urgency, and already he could begin to see the plan. The interior of the house was being carefully demolished without touching the outer walls. Summers with hammer and chisel was ripping out the skirting-boards in the ground floor dining-room: he had already smashed the panels of the door. In the same room Joe was heaving up the parquet blocks, exposing the soft wood floor-boards over the cellar. Coils of wire came out of the damaged skirting and Mike sat happily on the floor, clipping the wires. On the curved stairs two of the gang were working hard with an inadequate child's saw on the banisters – when they saw Blackie's big saw they signalled for it wordlessly. When he next saw them a quarter of the banisters had been dropped into the hall. He found T. at last in the bathroom – he sat moodily in the least cared-for room in the house, listening to the sounds coming up from below. 'You've really done it,' Blackie said with awe. ‘What's going to happen?' 'We've only just begun, T. said. He looked at the sledge-hammer and gave his instructions, ‘You stay here and break the bath and the wash-basin. Don't bother about the pipes. They come later.' Mike appeared at the door. ‘I've finished the wire, T.,' he said. 'Good. You've just got to go wandering round now. The kitchen's in the basement. Smash all the china and glass and bottles you can lay hold of. Don't turn on the taps – we don't want a flood – yet. Then go into all the rooms and turn out drawers. If they are locked get one of the others to break them open. Tear up any papers you find and smash all the ornaments. Better take a carving-knife with you from the kitchen. The bedroom's opposite here. Open the pillows and tear up the sheets. That's enough for the moment. And you, Blackie, when you've finished in here crack the plaster in the passage up with your sledge-hammer.' 'What are you going to do?' Blackie asked. 'I'm looking for something special,' T. said. It was nearly lunch-time before Blackie had finished and went in search of T. Chaos had advanced. The kitchen was a shambles of broken glass and china. The dining-room was stripped of parquet, the skirting was up, the door had been taken off its hinges, and the destroyers had moved up a floor. Streaks of light came in through the closed shutters where they worked with the seriousness of creators – and destruction after all is a form of creation. A kind of imagination had seen this house as it had now become. Mike said, 'I've got to go home for dinner.' 'Who else?' T. asked, but all the others on one excuse or another had brought provisions with them. They squatted in the ruins of the room and swapped unwanted sandwiches. Half an hour for lunch and they were at work again. By the time Mike returned, they were on the top floor, and by six the superficial damage was completed. The doors were all off, all the skirtings raised, the furniture pillaged and ripped and smashed – no one could have slept in the house except on a bed of broken plaster. T. gave his orders – eight o'clock next morning – and to escape notice they climbed singly over the garden wall, into the car-park. Only Blackie and T. were left; the light had nearly gone, and when they touched a switch, nothing worked – Mike had done his job thoroughly. How does Greene make the boys' actions at this point in the story so disturbing?
