At this moment they were joined by the coastguard officer.
"He has done us again," he said. "We have been investigating these outhouses thoroughly, and there is no question that he has had smuggled goods here. We found a clever hiding-place in that cattle-shed. It struck me that it was a curious thing that there should be a stack of hay built up right against the side of it. So we took down a plank or two, and I was not surprised to find that there was a hollow in the stack. One of the men stamped his foot, and the sound showed that there was another hollow underneath. We dug up the ground, and found, six inches below it, a trapdoor, and on lifting it discovered a hole five or six feet deep and six feet square. It was lined with bricks, roughly cemented together. It is lucky for him that the place is empty, and I should think that after this he will go out of the business for a time. Of course we cannot arrest a man merely for having a hidden cellar; I fancy that there are not many houses on the marshes that have not some places of the sort. Indeed, I am rather glad that we did not catch him, for in other respects Nibson is a decent, hard-working fellow. Sometimes he has a glass or two at the 'Lobster Smack,' but never takes too much, and is always very quiet and decent in his talk. I doubt whether the men would have found that hiding-place if I had not been there; they all know him well, and would not get him into a scrape if they could help it, though there are some fellows on the marshes they would give a month's pay to catch with kegs or tobacco."
The door of the house opened, and the three women and Nibson came out with Walter, who was now dressed in the clothes that they had brought down for him.
While the others were getting ready to enter the boat the officer took Nibson aside.
"You have had a close squeak of it, Nibson; we found your hiding-place under the stack, and it is lucky for you that it was empty. So we have nothing to say to you. I should advise you to give it up, my man; sooner or later you are bound to be caught."
The man's brow had darkened as the officer began, but it cleared up again.
"All right," he said; "I have been thinking for the last half hour that I shall drop the business altogether, but when a man once gets into it, it is not so easy to get out. Now that you have found that cellar, it is a good excuse to cut it. I can well say that I dare not risk it again, for that, after so nearly catching me, you would be sure to keep an extra sharp eye on me in the future."
"You give me your word for that, Nibson?"
"Yes, sir; I swear off it altogether from the present day."
"Good. I will take your word for it, and you can go in and come out as you like without being watched, and you need not fear that we shall pay you another visit."
