The two stories I liked were the other two novelettes:
1. Controlled Experiment by Tom Purdom -- a man who killed a police officer is placed in a public environment with people paid to live near as an experiment.
2. Sails the Morne by Chris Willrich -- a cargo ship with three hostile ambassadors hauls them and a portion of The Book of Kells to an exposition on another planet. The BoK is wanted by many people and must be preserved.
