Not my very favorite in this series so far, but still an excellent mystery/adventure.
Miles Vorkosigan and his cousin are sent as diplomatic envoys to a state funeral on Cetaganda. Basically, all they’re expected to do is to show up and look suitably grave.
However, the minute their spaceship docks, a mysterious assault occurs. In a combination of diplomatic tact and egotistical curiosity, Miles stays silent about the event, and embarks on solving the mystery himself.
Murder, politics, an enigmatic beauty, and a colorful society all come into play in a fast-moving story.
