It was now Merriman’s turn to hesitate. Although Madeleine Coburn had been in his thoughts more or less continuously since he returned to town, he had never mentioned her name, and he was not sure that he wanted to now.
‘Sorry I spoke, old man,’ Hilliard went on. ‘Don’t mind answering.’
Merriman came to a decision.
‘Not at all,’ he answered slowly. ‘I’m a fool to make any mystery of it. I’ll tell you. There is a girl there, the manager’s daughter. I met her in the lane when I was following the lorry, and asked her about petrol. She was frightfully decent; came back with me and told her father what I wanted, and all that. But, Hilliard, here’s the point. She knew! There’s something, and she knows it too. She got quite scared when that driver fixed me with his eyes, and tried to get me away, and she was quite unmistakably relieved when the incident passed. Then later her father suggested she should see me to the road, and on the way I mentioned the thing—said I was afraid I had upset the driver somehow—and she got embarrassed at once, told me the man was shell-shocked, implying that he was queer, and switched off on to another subject so pointedly I had to let it go at that.’
Hilliard’s eyes glistened.
‘Quite a good little mystery,’ he said, ‘I suppose the man couldn’t have been a relation, or even her fiancé?’
‘That occurred to me, and it is possible. But I don’t think so. I believe she wanted to try to account for his manner, so as to prevent me smelling a rat.’
‘And did she not account for it?’
‘Perhaps she did, but again I don’t think so. I have a pretty good knowledge of shell-shock, as you know, and it didn’t look like it to me. I don’t suggest she wasn’t speaking the truth. I mean that this particular action didn’t seem to be so caused.’
There was silence for a moment and then Merriman continued:
‘There was another thing which might bear in the same direction, or again it may only be my imagination—I’m not sure of it. I told you the manager appeared just in the middle of the little scene, but I forgot to tell you that the driver went up to him and said something in a low tone, and the manager started and looked at me and seemed annoyed. But it was very slight and only for a second; I would have noticed nothing only for what went before. He was quite polite and friendly immediately after, and I may have been mistaken and imagined the whole thing.’
‘But it works in,’ Hilliard commented. ‘If the driver saw what you were looking at and your expression, he would naturally guess what you had noticed, and he would warn his boss that you had tumbled to it. The manager would look surprised and annoyed for a moment, then he would see he must divert your suspicion, and talk to you as if nothing had happened.’
‘Quite. That’s just what I thought. But again, I may have been mistaken.’
They continued discussing the matter for some time longer, and then the conversation turned into other channels. Finally the clocks chiming midnight aroused Merriman, and he got up and said he must be going.
Three days later he had a note from Hilliard.
‘Come in tonight about ten if you are doing nothing,’ it read. ‘I have a scheme on, and I hope you’ll join in with me. Tell you when I see you.’
It happened that Merriman was not engaged that evening, and shortly after ten the two men were occupying the same arm-chairs at the same open window, their glasses within easy reach and their cigars well under way.
‘And what is your great idea?’ Merriman asked when they had conversed for a few moments. ‘If it’s as good as your cigars, I’m on.’
Hilliard moved nervously, as if he found a difficulty in replying. Merriman could see that he was excited, and his own interest quickened.
‘It’s about that tale of yours,’ Hilliard said at length. ‘I’ve been thinking it over.’
He paused, as if in doubt. Merriman felt like Alice when she had heard the mock-turtle’s story, but he waited in silence, and presently Hilliard went on.
‘You told it with a certain amount of hesitation,’ he said. ‘You suggested you might be mistaken in thinking there was anything in it. Now I’m going to make a suggestion with even more hesitation, for it’s ten times wilder than yours, and there is simply nothing to back it up. But here goes all the same.’
His indecision had passed now, and he went on fluently and with a certain excitement.
‘Here you have a trade with something fishy about it. Perhaps you think that’s putting it too strongly; if so, let us say there is something peculiar about it; something, at all events, to call one’s attention to it, as being in some way out of the common. And when we do think about it, what’s the first thing we discover?’
Hilliard looked inquiringly at his friend. The latter sat listening carefully, but did not speak, and Hilliard answered his own question.
‘Why, that it’s an export trade from France to England—an export trade only, mind you. As far as you learnt, these people’s boat runs the pit-props to England, but carries nothing back. Isn’t that so?’
‘They didn’t mention return cargoes,’ Merriman answered, ‘but that doesn’t mean there aren’t any. I did not go into the thing exhaustively.’
‘But what could there be? What possible thing could be shipped in bulk from this country to the middle of a wood near Bordeaux? Something, mind you, that you, there at the very place, didn’t see. Can you think of anything?’
‘Not at the moment. But I don’t see what that has to do with it.’
‘Quite possibly nothing, and yet it’s an interesting point.’
‘Don’t see it.’
‘Well, look here. I’ve been making inquiries, and I find most of our pit-props come from Norway and the Baltic. But the ships that bring them don’t go back empty. They carry coal. Now do you see?’
It was becoming evident that Hilliard was talking of something quite definite, and Merriman’s interest increased still further.
‘I dare say I’m a frightful ass,’ he said, ‘but I’m blessed if I know what you’re driving at.’
‘Costs,’ Hilliard returned. ‘Look at it from the point of view of costs. Timber in Norway is as plentiful and as cheap to cut as in the Landes, indeed, possibly cheaper, for there is water there available for power. But your freight will be much less if you can get a return cargo. Therefore a priori, it should be cheaper to bring props from Norway than from France. Do you follow me so far?’
Merriman nodded.
‘If it costs the same amount to cut the props at each place,’ Hilliard resumed, ‘and the Norwegian freight is lower, the Norwegian props must be cheaper in England. How then do your friends make it pay?’
‘Methods more up to date perhaps. Things looked efficient, and that manager seemed pretty wideawake.’
Hilliard shook his head.
‘Perhaps, but I doubt it. I don’t think you have much to teach the Norwegians about the export of timber. Mind you, it may be all right, but it seems to me a question if the Bordeaux people have a paying trade.’
Merriman was puzzled.
‘But it must pay or they wouldn’t go on with it. Mr Coburn said it was paying well enough.’
Hilliard bent forward eagerly.
‘Of course he would say so,’ he cried. ‘Don’t you see that his saying so is in itself suspicious? Why should he want to tell you that if there was nothing to make you doubt it?’
‘There
