> - he works A LOT (usually not shown on screen, but sometimes mentionned by him, and you can infer that a given piece of information took a lot of time to discover)
One episode where they actually showed some of that is the one where the murderer was the architect of a high-rise building. He needed the plans or some time with the building authority to have something explained to him, and he was shown waiting in line for a whole day with all the people applying for building permits, getting pushed from office to office, etc.
I could be mixing it up with another episode but I think that was the one where he needed to get a permit to excavate a concrete foundation under the pretense of looking for a body (to bait the murderer into subsequently depositing the body there after it had already been excavated and searched).
