‘How did you come to be on the beach?’ asks Judy hastily.

‘We’re doing a survey for the university on coastal erosion. We’re surveying all the north-east Norfolk beaches. We’ve made some interesting finds as well. Palaeolithic hand axe at Titchwell, a Roman bracelet at Burgh Castle, lots of shipwrecks. Steve was examining the cliffs here when he saw the rockfall. The bones were in the gap behind. It looks like they were buried fairly deeply but the earth got dislodged when the stones came down.’

‘How come you’re discovering these things?’ asks Judy, as they walk back along the cliff path. ‘If the sea’s advancing, wouldn’t it cover everything up?’

Clough is glad she has asked this. He’d wanted to but was scared of looking stupid in front of Trace.

‘Tides change,’ says Trace shortly. ‘Sand gets moved; parts get silted up, other parts uncovered. The pebbles get pushed further up the beach. Things that were buried become exposed.’

‘Like our bones,’ says Steve. ‘They may have been buried well above the tidal line but the water’s getting closer, it’s wearing the earth away. Then part of the cliff came down on top of them.’

‘Did you get a good look at them?’ asks Clough.

‘Not really,’ says Steve. ‘Tide was coming in too fast. We didn’t want to get stranded on the wrong side of the beach. But, just at a glance, I’d say we were looking at more than one body.’

Clough and Judy exchange glances. ‘Definitely human?’

‘In my humble opinion, yes.’

‘We found something else too,’ says Trace, whose opinions are never humble.

They have reached the pub. Its sign, which, rather tactlessly, shows a man falling off a cliff, creaks in the gathering wind. They can see Ted through the window, raising a pint to his lips. In the yellow light from the window, Trace holds out something that looks a bit like loft insulation, a small ball of fluffy, yellowish fibres.
