Several ideas were swimming around Horton’s head but he shelved them for the moment to concentrate on what more Williams had to tell him.
‘Walpen began to invest his money in building projects and most specifically in the boom in building in Ventnor as it became a health resort. In 1844 he married the wealthy daughter of a landowner. She inherited when her father died, only to die a year later in 1856, childless, making William Walpen even wealthier. He then married a woman thirty years younger than him, in 1862, Mary, who after many miscarriages and stillbirths finally produced a son, Elliott, in 1872, dying herself in childbirth. William didn’t remarry but put his energies into his business which now included shipping, hotels and land. He died in 1893 leaving it all to Elliott, then aged twenty-one. But Elliott, with a good education and a quick brain, was an even better businessman than his father. He also got heavily involved in Cowes Week and indulged his passion for yacht racing and the America’s Cup and was a keen astronomer. He married Julia in 1905, but she died in 1914, so, like his father before him, Elliot remarried a young woman, Lisa, in 1920, who produced Sarah Walpen in 1921. Elliot died in 1935 and his wife in 1955. Sarah took herself off to America in 1957 and that was the last anyone heard of her.’
Thoughts hurtled through Horton’s mind. So much added up: sailing. . Cowes Week. . the Raoul Dufy painting. . astronomy. . Hazleton’s telescope. . the Thea Porter dress that Yately had been wearing when his body had been found, possibly purchased in America, and in 1976 Sarah Walpen would have been fifty-five and within the age range Dr Adams had said the buyer of the dress might have been. But none of these were evidence of why Yately was killed.
Williams said, ‘Sarah Walpen must have died in the States and I’m not aware that she ever married. The line died out with her and I told Mr Yately this.’
‘How did he seem when you told him?’ asked Horton eagerly.
Williams considered this for several moments. ‘Satisfied. Yes, that’s how I’d describe it. And possibly even triumphant.’
At last Horton was beginning to feel a little triumphant himself. His visit here hadn’t been a waste of time, on the contrary it had given him the key to the case and that key was Sarah Walpen. Colin Yately had discovered, or had had an idea about what had happened to her. Horton did too.
When he ascertained that Ian Williams could contribute no more to the case, Horton quickly and warmly thanked him and hurried outside, where he drove a short distance away before calling Uckfield. Quickly, he gave the Super a potted summary of what Williams had told him, ending with, ‘We need to find out if Sarah Walpen died in the States, but it’s my belief she didn’t. I think she returned to the Isle of Wight and Hazleton killed her and stole her possessions to fund his lifestyle. I think Sarah Walpen arranged to buy a house here, the place of her birth. She asked Wallingford and Chandler to act for her in the purchase of the property. They did, or rather Arthur Lisle did. On her return Hazleton struck up a friendship with her, before killing her and stealing from her so he could buy that big house on the cliff top and retire from Wallingford and Chandler to live the life of a gentleman. When Yately began his passion for local history he discovered the Walpens and was curious to trace the last of the line, Sarah. He mentioned it to his new friend who shared the same interest, Arthur Lisle, and Lisle recalled acting on the property purchase for Sarah. He couldn’t remember what property she’d purchased, hence his request to see the archives files.’
‘But there’s no Sarah Walpen named in that file,’ protested Uckfield.
‘Exactly, because Hazleton, as office manager, never filed the papers. And he erased all trace of her from the office records, so it was never entered on the computer.’
‘And when Lisle discovered this he called on Hazleton,’ interjected Uckfield excitedly.
‘Yes, but initially without mentioning Sarah Walpen. Remember Lisle checked the files two weeks ago, a week after Yately had consulted Ian Williams for the third time. I think Lisle bided his time, doing further research with Yately, until he was certain about Sarah Walpen. Then last week Lisle must have told Hazleton that he and Yately knew the truth. Hazleton must have fobbed them both off, saying he’d confess, and then lured Yately to meet him in the bay beneath his house where he killed him.’
‘Could he have the strength for that?’
‘Dr Clayton says that Hazleton was very fit and strong for his age and he could have surprised Yately. He knocked him out and then bound and gagged him.’ But there were still things that didn’t add up. He thought back to Dr Clayton’s report on Colin Yately’s death. He’d been tied up and almost drowned until the poor man had given his tormentor the information he wanted. Horton suspected that the information was what was contained in his historical notes about the Walpens. Could Hazleton have been physically capable of that? There were other anomalies too.
Frowning, he added, ‘I know that doesn’t account for Yately wearing what I think must have been one of Sarah Walpen’s dresses. Hazleton would hardly have wanted to draw attention to that, unless it was some kind of sick joke. And it doesn’t explain how Yately ended up in the Solent when Hazleton didn’t have a boat.’
‘Lisle had one though,’ said Uckfield. ‘Perhaps Hazleton persuaded or bribed Lisle to keep quiet about it. But Lisle then realizes he’ll be at Hazleton’s mercy, he collects all the evidence from Yately’s flat, i.e. the notes, visits Hazleton and kills him. Then he kills himself, unable to live with what he’s done.’
It made some kind of sense, but Horton still wasn’t sure.
Uckfield added, ‘I’ll get Trueman working on this Sarah Walpen. We’ve no sightings of Lisle for the weekend between Yately’s death and his showing up at Yately’s apartment, so perhaps he was hiding out at Hazleton’s house and that was when the guilt set in.’
Horton thought of those blows that had killed Hazleton. Could Arthur Lisle have inflicted them? People were capable of all sorts of terrible things when desperate, angry or provoked.
Uckfield continued, ‘We’ve got a sighting of Yately, but it’s for the wrong time. It’s the Monday before he was killed. He travelled to Southampton on the hi-speed Red Jet. Bought his ticket by cash, but one of the staff there recognized him. She’s been interviewed and it seems genuine but I can’t see how that helps us.’
And neither could Horton.
Uckfield said, ‘He probably went to do some sightseeing. Apparently he was carrying a briefcase and camera.’
‘I didn’t see either in Yately’s apartment, not on my first visit or our second one.’
There was a minute pause before Uckfield said curtly, ‘I’ll check with Taylor.’
Horton knew Taylor would confirm that neither had been in the flat, and Horton didn’t recall the witness mentioning Lisle carrying them. Lisle might already have put them in his car before returning to Yately’s flat when the witness had seen him. Or he could have put both in the briefcase, unless Yately had taken them with him when he’d met his killer. And why would he do that? Because the briefcase and camera contained something that would incriminate the killer in the death of Sarah Walpen. Horton’s pulse quickened. And if that were so, then had Yately gone to Southampton on the Monday before his death to collect and photograph the final piece of evidence? What was it? Horton needed to think and there was one place to do it: Victor Hazleton’s house.
