Inspector Morimoto and the Two Umbrellas

Using her powers of deductive reasoning, Suzuki helps Morimoto develop a hypothesis that involves espionage, secretive trips on the bullet train, deception, and double deception. Morimoto knows that a provincial inspector such as himself does not impress the Special Branch investigator--especially not when all Morimoto appears to be doing is collecting umbrellas--but perhaps Morimoto will have the last laugh?
