Stealing Barley in Ur III: a Detective Story?

This contribution is a little token of friendship for the Jubilee. Franco (Francesco Pomponio) is a good friend since many years and, as many of the readers probably know, he is not only one of the best assyriologists of his generation (and beyond), but also a professional expert of thrillers and detective stories. This is the reason why I decided to sort out of the Ur III documentation, one of his main field of expertise, one peculiar story they seem to tell, probably related to a criminal action referring to barley theft, in the hope that Franco will find it intriguing enough for his sophisticated literary taste.
