John Duquesne: Crime On A Government Reservation-Murder.
Two murders, 10 years apart, are linked by Inspector Erskine, giving him clues to solving both.
Here, The FBI meets CSI. We see the skeleton of the murder victim; the skull has a hole in it, where the victim was apparently shot. This was perhaps the most graphic scene of a murder in the series' history. Even then, the skeleton is otherwise pristine looking. Remember, this was 1968, and J. Edgar Hoover was running the bureau.
Burt Reynolds makes his second of two appearances on the series in this episode. In early 1968, he was still not the megastar he would become in the 1970s. He had been on Gunsmoke from 1962 to 1965, and Hawk in 1966. Burt Reynolds would later star in another QM series, Dan August (1970-1971).
