The Cosmic Computer by H. Beam Piper

There were no bands or speeches when they came in this time. A lot of contragravity vehicles circled widely around the spaceport, but except for a few news-service cars, the police were keeping them back of a two-mile radius around the landing-pits. A couple of gunboats were making tight circles above, and on the dock were more vehicles and a horde of police and guards.

When Rodney Maxwell came across the bridge from the dock after they opened the airlocks, he was followed by a dozen Barton-Massarra private police, as villainous-looking a collection of ruffians as Conn had ever seen. He was wearing a new suit, with a waist-length jacket instead of the long coat he usually wore, and there was a holstered automatic on each hip. In Litchfield, he never carried more than one pistol, and Storisende was supposed to be an orderly place where nobody needed to go armed. More than anything else, that told Conn approximately what had been going on while he had been on Koshchei.
