I wrote my lawyer's address on a piece of paper. 'I would be obliged if you would let me know the results of your investigation. You can write to that address.'

'I will let you know, M. Trevelyan. I am sure there will be a simple explanation.' He half stood up, clearly dismissing me.

I went immediately to the British Consul and got no joy. He was urbane and civil, pointing out that everything Mac-Donald had said was true and that the only thing to do was to wait. 'They'll investigate the matter, don't you worry, Mr Trevelyan. If old Schouten has made a mistake they'll find out.'

But he didn't sound convincing even to himself.

I said, 'What kind of man is this Schouten? I gather you know him.'

The consul shrugged. 'An old Islands type – been here for years. He's done some good work in the past.'

'But not lately?'

'Well, he's getting old and'

'Hitting the bottle,' I said viciously.

The consul looked up sharply. 'Don't blame him too much for that. He lost his entire family when the Japs invaded New Guinea.'

I said bitterly, 'Does that excuse him for killing his patients?'

There was no reasonable answer to that, and I pulled myself together and changed the subject slightly.

'Have you heard of a man called Jim Hadley?'

'A big Australian?'

'That's the man.'

'Of course he's never been in here,' said the consul. 'We've no official connection, but I've seen him around. He's well known here as a rather hard-headed type, not a man to be crossed I'd say. Your brother chartered his schooner for a while.'

'Is he really that tough?'

He frowned. 'Very much so. Not a consular tea party type at all. I wouldn't recommend him.'

'What about a man called Kane?'

'Is that the other Australian? His partner, I think – I've seen him with Hadley. It's the same answer, I'm afraid; I've never spoken to him.'

Tell me honestly – do you think the administration is dragging its heels in this matter?'

He sighed. 'I'll have to speak bluntly, Mr Trevelyan. When your brother died he was on the run from the police. He was suspected of murder.' As I was going to interrupt he raised his hand. 'Now, don't tell me that's ridiculous. Most murderers have brothers, like yourself, who refuse to believe anything ill of their kin, especially at first hearing.'

That wasn't what I was going to say, but I kept my mouth shut.

'When he died, complete with death certificate signed by a qualified medical man, the police called off the hunt, and quite naturally so in my opinion. At the present time the administration has a hell of a lot on its plate, and they had no reason to suspect anyone else. But they'll get around to investigating the new evidence you've brought them sooner or later.'

'When the trail is totally cold.'

'I do see your point,' he said. 'I don't think I can do anything about it. But I'll try.'

And with that I had to be content.

When I reboarded Esmerelda I felt blue. I think I had expected my news to come with a devastating shock, and it had been dismissed as a hiccup. Clare was on deck and she said sunnily, 'Isn't this a beautiful place?'

'It stinks,' I said sourly.

'What are you mad at? You look as though you wouldn't care if the whole island sank into the sea.'

'It's these damn colonial French. Justice – but at a snail's pace. The British here aren't much better either.'

'No dice with the Governor?'

'Oh, they'll make a new investigation in three months – or three years. He doesn't want to lose his precious Dr Schouten. If he looks too closely he might have to arrest the doctor for unprofessional conduct and he doesn't want to do that, so he's going easy on the whole thing – sweeping it under the carpet in the hope that it'll be forgotten. He's got much more important things to do than to find Mark's killer.'

She was sympathetic and I began to loosen up a little. After a while I even felt cheerful enough to ask her to dine with me, and to my delight she agreed at once. I excused myself and went in search of Geordie, whom I found tinkering with the engine in company with two of the crew. Everyone else had vanished ashore. I took Geordie aside and told him what had happened.

He wiped the oil from his hands and said, 'Then you're stymied.'

'Looks like it, as far as authoritative aid goes.'

'Now's the time to put some pressure on Campbell. You won't get anywhere without him if you want to see Schouten. It's a pity you can't interpret one of those drawings to read Tanakabu – or perhaps you can scare up some good scientific reasons for going there.'

'As well there as anywhere,' I said morosely. 'I'll work on it.'

I spent the rest of the day wandering around the town and picked out a restaurant for the evening, and when it came Clare and I took ourselves off for an enjoyable time during which we both avoided any of the subjects concerning the voyage, and got to know each other better. Campbell had booked himself and Clare into a hotel for the time we were to stay in Papeete, but I had declined his suggestion that I too make such an arrangement, so at the end of the evening I escorted Clare to her new temporary home and came back to the ship feeling weary but reasonably happy.

Early the next morning I saw the Eastern Sun enter harbour. Geordie disappeared with Ian and Jim, and I wandered on deck to find Danny Williams just reboarding.

'Morning, Mike,' he said. 'Just back from me detective stint.'

'What's all this?'

The skipper arranged for some of us lads to keep an eye on Kane. Yesterday he was at the post office and suchlike, and then he holed up in a spot called Quin's Bar. I had Nick follow him today, and I've sent Bill down to hang around Quin's again – we think it's his meeting-place. Yesterday he was asking for someone there.'

'Good enough,' I said. 'Why not yourself, though? Tired of playing copper?'

'I thought I'd better pull out. I followed Kane all over Panama and I thought that if I did the same here he might twig.'

I nodded in satisfaction. Danny was using his brains. After a while Campbell and Clare came on deck, clearly rested and ready for a fresh start, and I decided that this was as good a time as any to work on him. But he anticipated me.

'Clare's been telling me that you want to go and see this Schouten.'

I looked at Clare. I hadn't told her that but she must have been reading my mind, and I was grateful. I said, 'Under the circumstances, I thought it might be a good idea.'

Campbell frowned. 'I don't know about that.' He dug into his pocket and produced a letter. 'Suarez-Navarro are on the move again – heading towards Rabaul. They should be there by now.'

'Do you know if they're doing any dredging?'

He shook his head. 'My man doesn't say, but I don't think he could know without a flyover.'

'Do you want to follow them?'

Campbell shook his head again irritably as though shaking flies away. 'It's not what I want to do. You don't seem to know where to go next, and apparently Ramirez does. Maybe we should follow him.'

I looked up and saw a small party coming on board, Paula Nelson diminutive between Ian and Jim, Geordie shepherding her with her suitcase. 'Miss Nelson's here,' I said. 'Let's see where this leads us. If she can identify Hadley for me here we may not have to go and see Schouten.'

Campbell and Clare had been told that Paula was coming to Papeete and were both full of curiosity about her. I went over to greet Paula, who looked frankly delighted to see me, and introduced her. I cocked an eye at Ian, who grinned easily. 'No trouble,' he said. 'No one tried anything.'

Thanks, fellows. We're glad to see you, Paula. Did you have a good trip?'

'It was wonderful! I've never been on one of those big cruise ships before. And say – I hope you don't mind but I didn't work my passage. It was kind of fun to be one of the tourists for a change.'
