But it was too late. With another deep growl the car moved off and started to gather speed across the sand. I stopped and dropped to my knees, trying to gulp deep lungfuls of air, my heart racing. The car hurtled away from me, the engine roar fading as Miss Havisham tore along the hard sand. I watched it go at medium speed to the far end of the beach, then turn in a large arc for the first of her two runs. The engine growled again, rising to a high scream as the car gathered speed, the driving wheels throwing a shower of sand and pebbles far behind it. I willed her to be safe and for nothing to happen, and indeed, nothing did until she was decelerating after the first run. I was breathing a sigh of relief when one of the front wheels broke loose and was dragged beneath the car, throwing it up into the air. The front edge of the bodywork dug into the sand and the car swerved violently sideways. I heard a cry of fear from the small crowd and a series of sickening thuds as the car rolled end over end down the beach, the engine screaming out of control as the wheels gripped nothing but air. It came to rest right way up not five hundred yards from me, and I ran towards it. I was three hundred yards away when the petrol tank ignited in a mushroom of fire that lifted the three-ton car from the sand. When I got there I found that by some miracle she had survived. Perhaps it would have been better if she hadn't – Miss Havisham was horribly burned.

'Water!' I cried. 'Water for her burns!'

The small crowd of onlookers were hopeless and could do nothing but stare at us in shock.

'Thursday?' she murmured although she couldn't see me. 'Please take me home.'

I'd never jumped dual, taking someone with me, but I did it now. I jumped clean out of Pendine and into Great Expectations, right into Miss Havisham's room at Satis House, next to the rotting wedding party that never was, the darkened room, the clocks stopped at twenty to nine. It was the place where I had first seen her all those weeks ago, and it would be the place I saw her last. I laid her on the bed and tried to make her comfortable.

'Dear Thursday,' she said. 'They got to me, didn't they?'

'Who, Miss Havisham?'

'I don't know.'

She started coughing and for a moment I didn't think she would stop.

'You are close to me, my dear – they will come for you next!'

'But why, Miss Havisham, why?'

She grabbed my wrist and stared at me with her piercing grey eyes which had not wavered in their resolve for even one moment.
