Dead Man's Wharf

'He took a chance on not knocking himself out, or getting seriously injured going over like that?'

'He was wearing a seat belt and braced himself for the impact. He wasn't driving fast. He also had Daniel strapped in. Once underwater, our killer swops places with Daniel; a body is much lighter underwater, and more manoeuvrable.' Horton could see Uckfield eyeing him incredulously over the rim of his beer glass. 'It might have taken a bit of shoving and pushing, but it can be done.'

'Only if our killer has the lungs of a seal.'

'He was wearing an aqua lung.'

'Wouldn't Daniel Collins have thought it odd this bloke getting into his car wearing an aqua lung?' Uckfield said sarcastically.

'I expect Daniel was too drunk to notice or able to speak, but the killer wasn't wearing the aqua lung then. It was on the back seat of the car. And under his normal clothes the killer was wearing a dry suit. When the car hit the water, our killer holds his breath, releases the seat belt, reaches for his aqua lung and regulator and starts breathing. He then struggles into the apparatus knowing he has to act quickly in case anyone saw the car go into the sea. He swims out through the driver's window and around to the rear passenger side and into the car. That's what was bothering me about the photographs taken of the car after the incident, I knew there was something odd about it but couldn't work out what. All the windows were open. At first I thought, like Dr Clayton, it was because Daniel wanted some fresh air to help him sober up but it was because the killer needed access.'

Uckfield was shaking his head, but Horton could tell it was in amazement rather than disagreement. 'This is one hell of a crafty beggar we're up against.'

'Yes and a meticulous planner.' Horton thought of his conversation with Gary Manners. This fitted him perfectly. Hadn't he said that he was a whizz at organization and health and safety? And this needed a mind that would think through every implication and part of the plan to the last detail. The only flaw was Manners said he couldn't dive any more on account of his illness. But Horton only had his word for that.

He said, 'Our killer manoeuvres Daniel into the driver's seat. If he had left it there, he would have got away with it, but he doesn't know that Daniel Collins is dead, and maybe he's the kind that likes to be doubly-sure. So he thrusts Collins's head against the windscreen and back again to make sure the poor man won't regain consciousness. Then he swims off-'

'Where?'

Horton had been giving that considerable thought. 'There are a number of options. He has a boat nearby and is able to reach it. He climbs in, starts the motor and returns to either Eastney or Hayling Island to the south, where his car is parked. Alternatively, on the high tide, he takes the boat to Broadmarsh to the north and the public slipway there, where he hitches it up to his car and drives away.'

Uckfield sunk some more beer. 'I'll get some officers checking.'

Horton continued. 'Or he could have resurfaced further along the shore to the south where he comes up on the beach, changes into some clothes he's left there behind a bush on Milton Common, and then walks away, returning later to collect his diving gear.'

'So we need to ask if anyone saw a man walking along the dual carriageway in either direction in the early hours of Christmas morning. I'll give a press conference tomorrow, and before you ask, yes, I told Madeleine that it was over between us.'

'How did she take it?'

'Threatened to make a noise. I told her that when it came to noise I could roar a hell of a lot louder than her. It seemed to shut her up. Pity really because I liked her and she was a right little-'

'There is another theory,' Horton interrupted, not wanting to hear about Uckfield's sexual prowess or Madeleine's come to that. 'Our killer took his boat northwards to the sailing centre, next to Oldham's Wharf, where he hitches it to a trailer on the back of his car and drives away, or it could still be there on the shoreline. The sailing centre's CCTV doesn't show any cars in the car park that night though.'

Horton could see Uckfield's mind ticking over. He added, 'I've run the details of Daniel Collins's method of death through the ACR and nothing like this shows up locally, though there have been one or two cases of bodies found in cars in other parts of the country. I've asked Trueman to look into them, but I don't think they're connected.'

'So who have we got in the frame for both Collins and Farnsworth's murders?' Uckfield asked sharply.

Horton sat forward. 'Gary Manners. He claims not to dive any more, has a phobia for it on account of the accident with Farnsworth, but we only have Manners' word for that. He says he acts as coxswain on the dives. Manners would have known about the row Farnsworth had with Oldham, so maybe he thought he could implicate Oldham in Farnsworth's death. It's also worth checking to see if Manners has ever visited Oldham's to carry out a health and safety inspection. Perhaps that's where he got the idea from. And he has good cause to hate Farnsworth on account of screwing up his career.' Horton briefly relayed the conversation he'd had with Manners at the crematorium.

'Manners could have lured Farnsworth to the sailing centre with the promise of some information or by threat. The uniformed patrol says they stopped Farnsworth as he was heading that way. Farnsworth was worried at the station in case he was going to be late for his appointment, but Manners hung on for him, perhaps he even saw DC Lee on the radio as we left the sub-aqua club, and guessed we might pull Farnsworth over. Under cover of darkness, Manners kills Farnsworth, then transports him in a boat to Oldham's Wharf where he manages to get Farnsworth ashore and throws him in the pit. He then arranges the body to look as though he'd fallen in.'

'Sounds good enough to me. What about Daniel Collins?'

'Manners knew Daniel Collins and had been diving with him on several occasions. Our only stumbling block there is why Manners would want Daniel Collins dead.'

And as far as Horton could see Manners had no connection with the Rest Haven Nursing Home.

'We'll ask him when we bring him in tomorrow morning, nice and early. Nothing like a dawn swoop to get them worried.' Uckfield grinned. 'Dennings can interview him.'

Uckfield must have seen that Horton looked about to protest because he quickly added, 'Manners has already spoken to you so a fresh face, and one as gruesome as Dennings', might frighten Manners into talking.' Uckfield drained his glass. 'Another?'

'No. I'm off home.'

'The boat, you mean?'

'Yes.' Horton stiffened at Uckfield's sneer.

'Why don't you get yourself a flat?'

'Why should I?'

'You're not still expecting to go back to live with Catherine, are you?'

Horton said nothing.

After a moment Uckfield added, 'Any more news from Catherine about Emma?'

'No.'

Uckfield hesitated and Horton thought here it comes — maybe this was the real reason we're here drinking like old buddies.

'Look, Andy, what's the sticking point between you and Catherine?'

So that was it? Horton curbed his anger at the thought that Catherine had gone blabbing to her friend Alison Uckfield and Alison had got her husband to do Catherine's dirty work. Once, and not so long ago, Uckfield had thought him capable of hitting Catherine because she had intimated to Alison Uckfield that's where her bruises came from, when it was overactive sex with that oaf she was dating.

Evenly he said, 'The sticking point, as you call it, Steve, is me wanting to spend time with my daughter. I don't think that's much to ask, and I don't mean for an hour every other Wednesday. I want something more permanent than that.'

'But how? In our job that's not always possible. Take this case, for example, or any serious crime. We don't keep office hours and neither do we work to any sodding European Time Directive. If we did the public would get less of us than they already do and the criminals would be laughing behind their murders, mugging and thefts. If you said that you could have Emma every weekend, or even every other weekend, how do you know you won't be called in to help in an investigation or be already deep into one?'
