London is encumbered by an environmental change that makes travel and viewing limited; this plot line may seem similar to some.
"Jericho" is not a series for the cerebrally limited or those who watch in distraction. This episode is an great example. Many plot lines run though the story. Small allusions and clues present briefly and obtusely. Many may be confused.
For those who watch attentively and love the plot line, it will enrich. Jericho deals with his rivals in the department. Family history is revealed. For those who follow there is an intricate plot line.
London's history brings back memories of another serial killer, the butcher. Suspects have history of World War II Burma and Japanese POW camps. Hollywood's World War II creation, "The Bridge Over The River Kwai" plays a role.
It is a good episode.
