In addition to examining the details of Lee's death, this episode narrated a proper investigation by a veteran police detective. It was very interesting to follow the investigative process of gathering leads, ruling them out based on evidence and 3rd party expert opinions, and following the trail to the most credible theory given the amount of time that's passed.
It did get me to research further and my one nitpick is with the theory of excessive heat related to his collapse a couple months earlier. AC had been turned off that time in order to avoid noise in a dubbing session. The fatal collapse, on the other hand, occurred in a more social and most likely comfortable setting. These are just details that could've been mentioned to rule out heat stroke (a theory from a Lee biographer and not the detective) but it didn't detract from the thoughtful and deliberate job of the detective and the doctor.
