Clint Adams has temporarily traded in the wide-open spaces for the big city—Philadelphia, to be exact. He's been summoned by his friend, railroad magnate Sam Fortune, and Fortune's really putting on the dog: all expenses paid, fine hotel, steak dinner...he's even thrown in a friendly female for the Gunsmith's entertainment.
Of course. Fortune wants something in return. He's about to ride the new Orient Express from Paris to Istanbul—and Clint's invited. Fortune suspects that a competitor wants to make sure he never reaches his destination. And Clint's convinced when someone tries to gun him down before the trip even begins.
