Gregg and Rex came the closest to the answer. In all six episodes, the dead body is transported by means of the killer's car. That is why "Any Old Port in a Storm" is not included. Ric Carsini's body was transported in his own car.

If "Uneasy Lies the Crown" ought to be included on this list, please correct me. I do not remember whether the body of Adam Evans was transported in the car of Wesley Corman or David Sherwin.

David, I thought including "Dagger" was very creative of you. While Sir Roger wasn't actually in the trunk of Nicky's little roadster, he was still inside a trunk which was tied to the car!

ooooo...i didn't think about that idea headache. but very true.

(and i still think you should get some credit...because you got it right from the proverbial 'get-go' )

"Dagger of the Mind" is the reason why I use the phrase "by means of the killer's car" instead of "in the killer's car." Good job.
