Lunch-time came and went, and it was not until four o'clock that Hollingsworth was able to report success in tracking down three of the four survivors.
'The other bloke, Samuel Patterson, seems to have vanished. He left Nottingham two years ago to take a job as a labourer on a farm near Norwich, but he quit after only a few months and nobody's heard of him since. The Norwich police are trying to trace him.'
The second man paid his gratuity in Nottingham, Arthur Marlow, was a patient in an Army hospital.
'He's got a leg wound that won't heal. He's been bedridden for a year.'
Before they had even left the platform at Folkestone station next morning Madden and Styles learned that Alfred Dawkins was not the man they were seeking. 'That's right, sir, only one leg. Didn't they say?' Detective Sergeant Booth of the Folkestone CID had come to the station to meet them. He was a thickset man with dark brown eyes and a watchful air. 'Lost it in the very last month of the war, or so I've been told.'
Studying the sergeant, Billy noticed the yellowed fingers of a heavy smoker. His trousers were a little loose at the waist, possibly the result of a diet, Billy surmised. He had resolved to become more observant.
To take note of things. He knew he was burdened with a wide-eyed quality: a sort of innocence that led him to make daft remarks and ask stupid questions, like the one that had caused him such embarrassment in the chief inspector's office the day before. It was obvious why Captain Miller had closed the case, once you thought about it. His trouble was, he didn't think about things enough. Or, rather, he opened his mouth first.
This line of reasoning had been reinforced by a conversation he had had with Madden on the train coming down from London. The inspector had seemed in better spirits. The haunted look Billy had grown accustomed to was less marked. He had gone to the trouble of explaining to the young constable why the case they were on was proving so hard to crack.
'Nearly all murders take place between people who know each other, so there's an obvious connection from the start. But this man kills people he's never met. At least, that's what we think, though we can't be sure. How does he pick them? What took him to Highfield and Bentham in the first instance? Is he a travelling salesman? Does he drive a van, or some other vehicle? Whatever job he has seems to take him around the country. Without a real lead, we have to accumulate all the information we can, all the details, no matter how trivial, because the answer may lie in one of them.'
That chimed with what Billy had been telling himself. Pay attention.
They rode through golden cornfields and orchards heavy with fruit. Then the hedgerowed fields stopped abruptly and Billy saw the silver glint of the sea below. Madden pointed to a collection of low buildings on the outskirts of the town.
'That's Shorncliffe Camp. It used to be five, no, ten times the size. The tents stretched for miles. Nearly every British soldier who went to France passed through here. Did you know that, Styles?'
Billy nodded. It was the first time he had heard the inspector speak about the war.
'Towards the end they got up to nine thousand a day. They marched them down to the town and straight on to the Channel steamers and across to France. At night there were illuminated fishing boats strung out in lines all the way to the French coast.'
On the platform at Folkestone Detective Sergeant Booth explained about Dawkins. (To Billy's satisfaction, he had lit up almost at once.) 'We haven't got his current address, sir. He moves a lot — trouble with landladies. But he's generally down in the port this time of day. I've no doubt we'll find him there.'
'He's not the man I hoped he might be,' Madden admitted. 'But I'd like a word with him just the same.'
Booth had a taxi waiting outside the station. It took them on a winding downhill route through the town. When they reached the port he told the driver to stop. Ahead of them Billy could see the harbour situated in a natural bay carved out of the chalky cliffs. In the foreground a small steamer was tied up at the wharf. A crowd of people, mostly women, were gathered in front of the gangplank. Smoke was issuing from the steamer's red and white funnel. Sergeant Booth pointed. 'There he is, sir, at the foot of the gangplank.'
Through the press of bodies Billy caught a glimpse of a figure on crutches.
'All those women — they're war widows going on a tour of cemeteries in France and Belgium. It's something they started last year. Perhaps you read about it?'
Madden shook his head.
'Alf Dawkins gets himself down here whenever there's a sailing, which is most days in the summer.
Stands there on his crutches with his medals pinned on. You'd be surprised how many ladies put half a crown in his hand. Probably worth a couple of quid to him. Afterwards he goes over to the pub' — Booth pointed to a line of buildings a little way down the jetty — 'buys himself a drink. Two or three more likely. That's how we know him. He's been up before the bench. Drunk and disorderly.'
'I don't want to talk to him here. We'll wait in the pub.' Madden's voice was terse.
Twenty minutes later, sitting in a taproom smelling of fish and stale tobacco smoke, they heard the toot of the steamer's whistle. At that moment the pub doors opened and Dawkins swung in on his crutches. Short and stocky, his pale face was disfigured by red blotches. Billy noticed that one of his eyelids blinked with a nervous tic.
Madden rose. 'I'll talk to him alone, if you don't mind.'
Booth raised an eyebrow at his departing figure.
'Doesn't say much, does he?'
Billy wanted to defend the inspector, but he couldn't think of a suitable response.
'Mind you, I wouldn't have his job.'
'What do you mean?'
'This Melling Lodge business?' Booth shook his head. 'Worst kind of case a copper can find himself landed with.'
'Why's that?'
'Because you're dealing with something you don't understand.' The sergeant dipped into his beer. 'Most people do things for reasons and criminals are no different. But this bloke!' He shook his head again.
'With a case like that, it's hard to know where to start.'
Billy watched Madden lead Dawkins away from the bar to a table in the corner. The inspector carried their glasses. He pulled out a chair for the other man and saw that he was comfortably settled.
'I remember a case I was on once.' Booth was speaking again. 'A young woman was murdered, strangled.
Her body was found in a field just outside of town. We got the bloke that did it. He kept a diary.
It was produced in evidence.'
'Did he mention the murder?' Billy was fascinated.
Booth nodded. 'But it's what he wrote — I've never forgotten it. "Warm weather. Rain in the afternoon. I killed a girl today."'
'That was all?' Billy was incredulous.
The sergeant shrugged. 'She was his first, thank God. But I remember thinking then, there must be people around us living another life from the one we live. It's as though they're from a different world. To understand them you'd have to get inside their heads, and what chance is there of that?'
Madden took Dawkins's glass to the bar and returned to their table with a fresh drink. He was smiling and nodding at the other man. Dawkins spoke, gesturing with his hands. He patted his trousered stump. He was grinning across the table at the inspector.
'How did you catch him?' Billy wanted to know.
'Through a little thing.' Booth drained his glass.
'He'd taken something from the girl he killed, a brooch shaped like a buckle with a piece of amber mounted in the middle. It was nothing special, but we gave out a description of it. A couple of weeks later a beat constable noticed a girl in the street wearing something similar. He asked her where she'd got it and she told him a young man had given it to her. Turned out he was the bloke.'
