But Quincy does not, and there have been a few such episodes scattered throughout the series, but usually the audience is in the dark at least in regards to the how of the case if not the who.
A couple of men have killed a third man with a drug overdose. They cover the crime by pushing the man and his car off a cliff. But the body falls out of the car before the car reaches the bottom. The two men plan to go down and investigate - Is the guy really dead, perhaps reposition the body - when they see a car coming and have to drive away in a hurry so they aren't spotted near the scene.
The Mr. Big who hired them to do the killing is not happy because at this point nobody is sure the victim is even dead. So he uses the drug habit of a young man to strongarm his father - a medical examiner - to fake the autopsy so that what really happened to the victim does not come out. Assuming the guy is even dead! The audience sees all of this. All Quincy knows is that a body from a car crash has been brought into the coroner's office for autopsy.
Meanwhile there is a new doctor working for the office of the medical examiner. The new doctor is a young lady - very young - and Quincy is hitting on her!!!! Over 40 years later this is very hard to watch - Mainly because she is being harassed and disrespected, but also because she appears to be young enough to be Quincy's daughter. The yuck factor is strong.
The new doctor looks at the autopsy findings on the murdered guy and finds results different from the older respected - and blackmailed - coroner who doesn't find that there are any signs of foul play. Will she be believed? Watch and find out.
