When the bike __3__ the frontier, Peter would stop the man and __4__ him take the straw off and untie it. Then he would examine the straw very __5__ to see __6__ he could find anything, after which he would look in all the man’s pockets __7__ he let him tie the straw again. The man would then put it on his bike and go off down the hill with it. Although Peter was always __8__ to find gold or other valuable things __9__ in the straw, he never found __10__. He was sure the man was __11__ something, but he was not __12__ to think out what it could be.

Then one evening, after he had looked __13__ the straw and emptied the worker’s pockets __14__ usual, he __15__ to him, “Listen, I know you are smuggling things __16__ this frontier. Won’t you tell me what it is? I’m an old man, and today’s my last day on the __17__. Tomorrow I’m going to __18__. I promise I shall not tell __19__ if you tell me what you’ve been smuggling.” The worker did not say anything for __20__. Then he smiled, turned to Peter and said quietly, “Bikes.”
