Because the first season has 13 episodes, something had to happen in "Beau Soleil." The plot advanced forward and we finally got pertinent facts about Rosie and what was was doing. Unfortunately, though, Rosie being part of an escort service is nothing shocking, and has been done on television plenty of times before. Furthermore, I hardly care about her as a character and this new revelation doesn't do anything for me.
On the plus side, it looks like Linden and Holder are finally on the right track and get the name Orpheus. The final scene was the most frightening ending to any episode, putting Linden alone in the direct path of the potential killer. But we also have to remember that every time it seemed clear the killer was found, it turned out to be wrong. Unless the writers finally changed their pattern after 12 episodes, it's doubtful Richmond is the killer, and there will probably be an easy excuse. Then again, Richmond could actually be the killer and dramatically change things up.
Remember my prediction back at the beginning that Jamie was the killer? Here's my scenario: Jamie knew Richmond was sleeping with Rosie, so he killed her to keep her quiet.
Score: 8.3/10
