'Is this a well-known book?'

'I never saw another copy; picked this up on a second-hand bookstall for threepence.'

'She looked at it, you say?'

'Yes, I'm certain of it.'

'Was she never on board you in September?'

'No; I asked them both, but Dollmann made excuses.'

'But _he--he_ came on board? You told me so.'

'Once; he asked himself to breakfast on the first day. By Jove! yes; you mean he saw the book?

'It explains a good deal.'

'It explains everything.'

We fell into deep reflexion for a minute or two.

'Do you really mean _everything_?' I said. 'In that case let's sail straight away and forget the whole affair. He's only some poor devil with a past, whose secret you stumbled on, and, half mad with fear, he tried to silence you. But you don't want revenge, so it's no business of ours. We can ruin him if we like; but is it worth it?'

'You don't mean a word you're saying,' said Davies, 'though I know why you say it; and many thanks, old chap. I didn't mean "everything". He's plotting with Germans, or why did Grimm spy on us, and von Bruning cross-examine us? We've got to find out what he's at, as well as who he is. And as to her--what do you think of her now?'

I made my _amende_ heartily. 'Innocent and ignorant,' was my verdict.

'Ignorant, that is, of her father's treasonable machinations; but aware, clearly, that they were English refugees with a past to hide.'

I said other things, but they do not matter. 'Only,' I concluded, 'it makes the dilemma infinitely worse.'

'There's no dilemma at all,' said Davies. 'You said at Bensersiel that we couldn't hurt him without hurting her. Well, all I can say is, we've _got_ to. The time to cut and run, if ever, was when we sighted her dinghy. I had a baddish minute then.'

'She's given us a clue or two after all.'

'It wasn't our fault. To refuse to have her on board would have been to give our show away; and the very fact that she's given us clues decides the matter. She mustn't suffer for it.'

'What will she do?'

'Stick to her father, I suppose.'

'And what shall we do?'

'I don't know yet; how can I know? It depends,' said Davies, slowly.

'But the point is, that we have two objects, equally important--yes, equally, by Jove!--to scotch him, and save her.'

There was a pause.

'That's rather a large order,' I observed. 'Do you realize that at this very moment we have probably gained the first object? If we went home now, walked into the Admiralty and laid our facts before them, what would be the result?'

'The Admiralty!' said Davies, with ineffable scorn.

'Well, Scotland Yard, too, then. Both of them want our man, I dare say. It would be strange if between them they couldn't dislodge him, and, incidentally, either discover what's going on here or draw such attention to this bit of coast as to make further secrecy impossible.'

'It's out of the question to let her betray her father, and then run away! Besides, we don't know enough, and they mightn't believe us.

It's a cowardly course, however you look at it.'

'Oh! that settles it,' I answered, hastily. 'Now I want to go back over the facts. When did you first see her?'

'That first morning.'

'She wasn't in the saloon the night before?'

'No; and he didn't mention her.'

'You would have gone away next morning if he hadn't called?'

'Yes; I told you so.'

'He allowed her to persuade you to make that voyage with them?'

'I suppose so.'

'But he sent her below when the pilotage was going on?'

'Of course.'

'She said just now, "Father said you would be safe." What had you been saying to her?'

'It was when I met her on the sand. (By the way, it wasn't a chance meeting; she had been making inquiries and heard about us from a skipper who had seen the yacht near w.a.n.geroog, and she had been down this way before.) She asked at once about that day, and began apologizing, rather awkwardly, you know, for their rudeness in not having waited for me at Cuxhaven. Her father found he must get on to Hamburg at once.'

'But you didn't go to Cuxhaven; you told her that? What exactly _did_ you tell her? This is important.'

'I was in a fearful fix, not knowing what _he_ had told her. So I said something vague, and then she asked the very question von Bruning did, "Wasn't there a _schrecklich_ sea round the Scharhorn?"'

'She didn't know you took the short cut, then?'

'No; he hadn't dared to tell her.'

'She knew that _they_ took it?'

'Yes. He couldn't possibly have hidden that. She would have known by the look of the sea from the portholes, the shorter time, etc.'

'But when the 'Medusa' hove to and he shouted to you to follow him--didn't she understand what was happening?'

'No, evidently not. Mind you, she couldn't possibly have heard what we said, in that weather, from below. I couldn't cross-question her, but it was clear enough what she thought; namely, that he had hove to for exactly the opposite reason, to say _he_ was taking the short cut, and that I wasn't to attempt to follow him.'

'That's why she laid stress on _waiting_ for you at Cuxhaven?'

'Of course; mine would have been the longer pa.s.sage.'
