oneâs own language to someone outside oneâs household. If you will put up with pot-luck I am sure we should both be gladââ he looked at his daughter ââif you would wait and take some dinner with us now. Tomorrow you could explore the woods, which are really worth seeing though monotonous, and if you are at all interested I should like to show you our little works. But I warn you the affair is my hobby, as well as my business for the time being, and I am apt to assume others have as great an interest in it as myself. You must not let me bore you.â
Hilliard, suspicious and critically observant, wondered if he had not interrupted a second rapid look between father and daughter. He could not be sure, but at all events the girl hastened to second her fatherâs invitation.
âI hope you will wait for dinner,â she said. âAs he says, we see so few people, and particularly so few English, that it would be doing us a kindness. Iâm afraid thatâs not very complimentaryââshe laughed brightlyââbut itâs at least true.â
They stayed and enjoyed themselves. Mr. Coburn proved himself an entertaining host, and his conversation, though satirical, was worth listening to. He and Hilliard talked, while Merriman, who was something of a musician, tried over songs with Miss Coburn. Had it not been for an uneasy feeling that they were to some extent playing the part of spies, the evening would have been a delight to the visitors.
Before they left for the launch it was arranged that they should stay over the following day, lunch with the Coburns, and go for a tramp through the forest in the afternoon. They took their leave with cordial expressions of good will.
âI say, Merriman,â Hilliard said eagerly as they strolled back through the wood, âdid you notice how your sudden appearance upset them both? There can be no further doubt about it, thereâs something. What it may be I donât know, but there is something.â
âThereâs nothing wrong at all events,â Merriman asserted doggedly.
âNot wrong in the sense you mean, no,â Hilliard agreed quickly, âbut wrong for all that. Now that I have met Miss Coburn I can see that your estimate of her was correct. But anyone with half an eye could see also that she is frightened and upset about something. Thereâs something wrong, and she wants a helping hand.â
âDamn you, Hilliard, how you talk,â Merriman growled with a sudden wave of unreasoning rage. âThereâs nothing wrong and no need for our meddling. Let us clear out and go on with our trip.â
Hilliard smiled under cover of darkness.
âAnd miss our lunch and excursion with the Coburns to-morrow?â he asked maliciously.
âYou know well enough what I mean,â Merriman answered irritably. âLetâs drop this childish tomfoolery about plots and mysteries and try to get reasonably sane again. Here,â he went on fiercely as the other demurred, âIâll tell you what Iâll do if you like. Iâll have no more suspicions or spying, but Iâll ask her if there is anything wrong: say I thought there was from her manner and ask her the direct question. Will that please you?â
âAnd get well snubbed for your pains?â Hilliard returned. âYouâve tried that once already. Why did you not persist in your inquiries about the number plate when she told you about the driverâs shell-shock?â
Merriman was silent for a few moments, then burst out:
âWell, hang it all, man, what do you suggest?â
During the evening an idea had occurred to Hilliard and he returned to it now.
âIâll tell you,â he answered slowly, and instinctively he lowered his voice. âIâll tell you what we must do. We must see their steamer loaded. Iâve been thinking it over. We must see what, if anything, goes on board that
