As expected the whole place was abandoned and only filled with boxes as both of them entered together, they began to observe their surroundings silently. Rachel was the first one to break the silence "Some of these boxes may actually contain goods and I don't think we have this much time to open all the boxes."
Robert handed her a knife "Tap a little on the top of the boxes, if it does not go in then it is filled with goods and if it does then it contains a person and the top is empty."
Rachel held the knife and gave him an appreciative look and then began to tap the boxes starting from one corner, Robert began on the other side of the room. It took them half an hour to go through all the boxes but none of them had anything unusual.
Rachel looked at Robert "What now?"
Robert didn't say anything instead he began to tap the walls with his knife, Rachel was confused "What are you doing?"
