Dead Man's Grip

every dark-coloured Yaris, regardless of whether it was grey or not. He wanted to eliminate any possible risk of the suspect slipping through the net, including a mistake being made by someone who might be colour blind.
    It was possible the boy was already abroad, despite the watch that had been put on all airports, seaports and the Channel Tunnel. There were private aircraft and private boats that could easily have slipped the net. But he was fairly certain that the Toyota Yaris belonging to Barry Simons was the one Tyler Chase had been driven in from the Regency Square car park. And if that was the case, Grace did not think he had left the Shoreham area.
    Checks had been carried out with the Harbour Master, the Port
Authority and the Coast Guard. All vessels that had sailed from Shoreham Harbour today had been accounted for. No cargo ship had passed through the lock after eight o’clock this evening. A few fishing boats had gone out, but that was all.
    Suddenly Stacey Horobin came over to him and said, ‘Sir, I have a Lynn Sebbage on the phone, from a firm of chartered surveyors called BLB. She’s asking to speak to Norman Potting – said she’s tried his mobile but he’s not picking up. She says she’s been working through the night to look for the information he asked her for, urgently, and she thinks she’s found it.’
    Grace frowned. ‘Chartered surveyors?’
    ‘Yes, called BLB.’
    ‘You mean chartered surveyors as in structural engineers ?’
    Horobin nodded. ‘Yes, sir, that area.’
    ‘What do they want at this hour of the morning?’
    ‘I don’t know.’
    ‘Where is DS Potting?’
    ‘DS Moy says she thinks he may have gone out to get something to eat, sir.’
    ‘OK, let me speak to the woman. Did you say Sebbage?’
    ‘Lynn Sebbage.’
    He picked up the phone and moments later she was put through. ‘Detective Superintendent Grace,’ he said. ‘Can I help you?’
    ‘Yes,’ she said. She sounded as fresh as if it was the middle of her normal working day. ‘I’m a partner in BLB. We’re very old-established chartered surveyors in Brighton. We had a visit from Detective Sergeant Potting late this afternoon, regarding the little boy who’s been abducted, saying he was looking for places around Shoreham Harbour where someone might be concealed. The Chief Engineer told him that he knew my firm, BLB, has done a lot of work at the harbour over the past century, particularly in the construction of the original coal-fired power station. He said he thought there was a tunnel bored then that’s been disused for decades.’
    ‘What kind of a tunnel?’ Grace asked.
    ‘Well, I’ve been hunting through our archives all night – they go back over a hundred years – and I think I’ve found what he was
referring to. It’s a tunnel that was built for the old power station, Shoreham B, about seventy years ago, to carry the electricity cables under the harbour, and it was decommissioned when the new power station was built twenty years ago.’
    ‘How would someone other than a harbour worker know about it?’
    ‘Anyone studying the history of the area could find it easily. It’s probably on Google if people look hard enough.’
    She then explained where the access to it was.
    A couple of minutes later, just as he thanked her and hung up, Glenn Branson walked in carrying two steaming mugs.
    ‘Brought you a coffee.’
    ‘Thanks. Want to come and take a ride? We could both do with a quick change of scenery.’
    ‘Where to?’
    ‘Somewhere in Brighton you and I have never been before.’
    ‘Thanks for the offer, boss man, but being a tourist at 1 a.m. doesn’t float my boat.’
    ‘Don’t worry. We’re not going boating – we’re going to go underwater.’
    ‘Terrific. This is getting better every second. Scuba-diving?’
    ‘No. Tunnelling.’
    ‘Tunnelling? Now? At this hour? You’re not serious?’
    Grace stood up. ‘Get your coat and a torch.’
    ‘I’m claustrophobic.’
    ‘So am I. We can hold hands.’

    ‘What do you think the chances are?’ Glenn Branson said, as Grace drove slowly along the road, peering to the left, looking for the building Lynn Sebbage had described. A strong wind buffeted the car and big spots of rain spattered on the windscreen.
    ‘One in a million? One in a billion? One in a trillion that he’s in this tunnel?’
    ‘You’re not trying to think like the perpetrator,’ Grace said.
    ‘Yeah, and that’s just as well, coz I’d be
