The contents of his house were being searched and his personal papers had been bagged up and Trueman's team were going through them and looking into Farnsworth's finances, which on first glance looked very healthy indeed. DC Marsden had the task of tracking down and interviewing Farnsworth's previous girlfriends, which, Horton thought, might take some time.
By the time he'd brought Cantelli up to date with the events of the previous day, Walters had arrived. He detailed him to find Chalky White, one of their more useful informers, and get him asking around the pubs and clubs to see if Marion or Ian Keynes had been trying to pass off stolen goods.
Horton handed the case notes on the armed robbery to Cantelli. 'Read through that, Barney, and see if it tallies with your memory. Is there anything missing or does anything strike you as unusual?'
Cantelli took the file. 'About Farnsworth's death — don't laugh at this, but it was something that Johnny, my nephew, said to me yesterday about treasure hunting.'
'You mean as in chests with gold sovereigns?' Horton teased.
'Not quite.' Cantelli smiled.
That was better. Horton was glad to see a spark of life back in the sergeant's dark eyes.
'Johnny says that diving is highly competitive,' continued Cantelli. 'And when it comes to wreck hunting there's big money to be made. Not only in discovering a long-lost wreck but also in the selling of antiquities.'
Horton thought back to his conversation with Ryan Oldham who had claimed the Solent was littered with rubbish and wrecks. Cantelli's theory might not be so far-fetched at that. Discovering something like the Mary Rose, Henry the Eighth's Tudor warship, would make someone's name in marine archaeological circles, which Farnsworth would have loved.
'Go on.'
'Say Daniel Collins discovers a wreck whilst out diving with Nathan Lester and Gary Manners. They're sworn to secrecy until they can confirm its significance and rightfully claim it, but Lester blabs to Farnsworth. Farnsworth approaches Manners and wants to muscle in on the act. But Manners hates Farnsworth on account of the accident years ago. And Manners wants the glory and fame for himself so he starts killing off his rivals, first Daniel Collins and then Nick Farnsworth.'
'Which means that Lester is his next victim, or would have been if we didn't have Manners here. Get Lester's home address. If Manners is our killer, then Lester will feel very relieved when he knows we've got him in for questioning, so relieved that he might tell us everything.'
Horton rang through the information to Uckfield, explaining Cantelli's theory, which drew a snort of disbelief, but Horton knew he'd put it to Manners. As he rang off another thought occurred to Horton. To Cantelli he said, 'Lester could have told Perry Jackson about the wreck. Maybe he wanted to take the credit for it.'
'Would he have killed Daniel Collins though?'
Horton considered the fact. He couldn't see Jackson swimming in and out of car windows, but he might have got Lester to do his dirty work for him. 'Let's ask him.'
'And this?' Cantelli indicated Ebury's file.
'Read it later.'
Cantelli pushed it in the drawer of his desk and hurried after Horton.
Fifteen minutes later Jackson opened the door of his hotel bedroom with a pained look on his face. 'What is it now?' he snapped, grudgingly letting them in.
'Packing, sir?' asked Cantelli, nodding at the holdall on the bed.
'I think that's what it's called, Sergeant,' Jackson replied with heavy sarcasm. 'I refuse to be kept a prisoner here any longer.'
'We asked to be notified when you left the hotel.'
'I haven't left. I am in the process of leaving,' Jackson said pedantically, stepping around Cantelli as he carried his clothes from the hotel wardrobe to the holdall. 'I am not a criminal and neither will I be treated like one.'
That remains to be seen, thought Horton. He said, 'When did you first meet Daniel Collins?'
'Who?'
Jackson didn't even pause in his packing. He was very good if he was lying.
Sternly Horton said, 'Mr Jackson, will you stop that and answer our questions, otherwise we'll have no option but to take you to the station.'
Jackson pulled up abruptly. 'You can't do that!'
'We can. So put down those socks and let's see if we can get this cleared up.'
Jackson glared at Horton before capitulating with a great deal of huffing and puffing.
'Well?' he demanded belligerently, glancing at his watch with the air of a man who has two minutes to spare and has started counting.
'Daniel Collins?' repeated Horton, folding himself into one of the armchairs opposite the bed whilst Cantelli sat in the other one. Horton looked pointedly at Jackson, who after a moment sat down heavily on the bed with a deep scowl.
'I've never heard of him.'
Horton decided to help him out. 'He used to dive with Nathan Lester. Didn't Lester mention him?'
'No.' Maybe Jackson was a good liar. Horton said, 'How did you feel when Nick was asked to give the keynote address at the international conference this June?'
Jackson looked surprised, was that at the change of subject or that Horton knew about the conference?
'What's this got to do with Nick's death?'
'I think we'd get through this interview much quicker if only one of us asks the questions.'
'I didn't feel anything. If Nick wanted to give the talk, then fine.'
'You weren't jealous?'
'Why should I be? I don't like that sort of thing.'
Oh, yeah, thought Horton, pull the other one.
'What sort of thing do you like, sir?' asked Cantelli.
Jackson swivelled his gaze. 'Diving, researching and writing. I don't spout humorous anecdotes or embellish fact with fiction. I am writing a book about my exploits on the wreck series based on facts, not the silly schoolboy pranks and adventures that Nick liked to conjure up. And if you don't mind — ' he glanced pointedly at his watch — 'I'm having lunch with my editor in London, and I have a train to catch.'
And if Collins had discovered an important wreck, wouldn't that make a nice bit of publicity for Jackson's book, not to mention perhaps a completely new commission?
'What will happen to the series now?' asked Horton.
'It will carry on as usual.'
'It can hardly do that with Nicholas Farnsworth dead,' Horton said, trying to goad Jackson into displaying some kind of emotion for his partner's death. He might just have well not bothered.
Jackson rolled his eyes and sighed. 'I meant the programme will continue.'
'With another diver?' Horton recalled that Kirkwood had said the series had been the brainchild of Perry Jackson, who had sold it to the production company, so he must have a say over his diving companion.
'Yes. I've already spoken to him. And he's a much better choice than Nick.'
That was quick work, thought Horton. Too bloody quick for his liking. He guessed production companies had a schedule to keep, especially if they were tied to a strict filming timetable, but Nick Farnsworth hadn't even been buried yet. Perhaps TV companies had understudies like the theatre did. He really didn't know much about them. 'How is he a better choice?'
'He'll give the series a more serious tone. Nick was always looking to sensationalize the programme, and his vanity was huge. He wanted to be a star. We're not the stars, I used to tell him, the wrecks we find and their history are the real stars, but Nick couldn't see that. I want to make the series more educational; something that is sadly lacking in our dire culture of dreadful reality television shows. The public need to be aware that we have a duty to protect our underwater heritage, and who better to dive with me and take over from Nick than Nathan Lester.'
