"One White Rose for Death" is an episode that some younger folks might find confusing. Let me explain...back before the fall of the Iron Curtain, people in these various communist nations were not allowed to freely travel. Why? Because when they saw how nice life in the West was, folks often left to live in countries like the USA, the UK and France (among others). But, to do this might mean risking your life or risking imprisonment.
Jessica is going to a concert being put on at the Kennedy Center in Washington, DC. The stars are a female violinist and her piano playing brother. However, in the middle of the concert, Jessica and her date are rushed out of the building and into a waiting limo...and are rushed to the British embassy. Why? Because the East German musicians are hidden in the trunk! And, the East German secret police are about to give chase!
So how does Jessica get to solve a murder when this is just an episode about two defectors? Well, once they are safely at the embassy, one of the embassy's residents is murdered! And, of course, Jessica does her thing.
This is a very good episode for one important reason...it's different. Considering how there is a lot of sameness to shows (after all, it ran for 12 seasons), it's nice to see an unusual plot.
