Kinda a lot of episodes were like that. The more interesting episodes I think it was more of a he was 'a sly little elf perched on his toadstool'. He was unassuming. He disguised himself to be invisible and would pick apart everything usually very methodically. He 'took a defect and used it as a tool'. Even the way he would blow people off was to be unassuming 'oh my boss he is a very exacting man', 'oh just a routine question'. When it was usually him looking for that information. He would many times make the perp 'self own' themselves by their own lies. The writers were also very good on making sure motive, means and opportunity were clearly picked apart in all ways. Apparently the whole crew was in on it and would make sure that the story stayed true. Making sure things were filmed so they did not contradict later or past actions. The 90s series was a bit less tight and more of the 'stick it to the rich'. They were enjoyable enough. But something was missing.
