Whetstone of the Mind: Jack Wellington UN Attaché

Jack is called to the Port Authority Warehouse to look at a bowl discovered inside a wall. The bowl leads him to a thief in Italy. The thief says he stole antiquities from a Library and Museum in Italy at the behest of an unsophisticated oil man from Oklahoma. This sends Jack across the US looking for antiquities stolen from a Library and Museum in Italy. In the back country of Oklahoma, he finds an assassin is trying to stop him. When he finds the stolen items in California, there is a surprise hidden in the midst of the stolen antiquities that leads him to the Vatican Library.
