The premises were surrounded by an old and dilapidated wall, but they noticed that along its top ran a row of formidable spikes, apparently of recent date. The front door of the mill-house faced the road. It was stoutly built of oak studded with nails, and was flanked on both sides by barred windows. The smuggling miller who built the place had evidently made himself secure against surprise.
When the dray drew up before the door, Pariset sprang down and jerked the iron bell-pull. From the driver's seat Kenneth saw a face appear for an instant at one of the windows. After a short interval the bolts were withdrawn, the door opened, and a man stood on the threshold. Kenneth tingled; he had recognised him instantly as the man who had been in conversation with Hellwig. He turned his head so as not to show his full face, pulled his hat lower over his eyes, and hoped that the recognition had not been mutual. And he listened anxiously, wondering how Pariset would acquit himself in his novel part, and wishing for the moment that Granger was in his place.
Pariset, however, was cool and collected. He took the bull by the horns.
"I am sorry I am late, monsieur," he said, "but the fact is that all our carters are called up for transport purposes. Being anxious not to disappoint a valued customer, my master has sent us out of the office. We shan't be able to come again, for we're called up ourselves--all through those pigs of Germans, who are said to be across the frontier. We shan't be able to deliver any more beer, I'm afraid. It's a wonder we've any horses left."
The German merely grunted in answer to this.
"We're in for a very bad time," Pariset went on, as he hoisted the end of the cask on to the doorstep. "Hadn't you better go back to Switzerland, monsieur? Pardon the suggestion, but we don't know what may happen. If these German pigs come south----"
"Just roll it into the lobby," interrupted the German. "Here's the money. By the way, have you seen an aeroplane in the neighbourhood?"
"Yes, we saw one an hour or so ago. It was flying north-east. I shouldn't be surprised if it was German. The pigs are capable of anything. But they'll get a reception that will surprise them. Our little army--but there! You know what your own army would do, and your turn may come in Switzerland sooner than you think. Thank you: I am sorry we shan't be able to serve you again, by the look of things."
He laid the cask in the lobby, pocketed the money, and returned to the dray.
Meanwhile Kenneth had seized the opportunity to take a careful look around. It was clear that it would not be easy to take the place by a rush without giving the inmates sufficient time to fire the mine beneath the bridge. The fact that the German had come to the door himself, instead of the deaf old countryman whom he was said to employ as a man-of-all-work, showed that he was on the alert. Nothing would be easier than to overpower the man himself; but if any noise were made in so doing his companions would instantly come to his assistance, and at the first sign that the plot had been discovered the bridge would be blown up. It seemed that the ruse would prove fruitless after all.
