Im doing the quest in ald-ruhn where there is a dwemer-artifact smuggler I have to expose. I just dont know how...because I dont find any artifacts in his house or on his person. What do I do?

The tube is on top of the table surrounded by pots. The pots is the same colour as the tube making is very very to hard to spot. So you will need to stand on the table to slowly check through the table. the table I'm talking about is northwest from the entry door.
