I hope the link works. The murder of the soldier starts at 33.20, the murder of the emissary starts at 48.58. Later we can see their two naked bodies in the morgue(50.12).
What excited me is the fact...
Nicolas le Floch. Season 3 ep 1. Very interesting episode with two handsome males being stabbed. There is also a naked scene of the two bodies in this episode.
