I was wrong to fear that the fourth series of "Spiral" would have run out of steam plot-wise. It proves compulsive viewing as ever, with at least half-a-dozen dramatic interwoven storylines, involving at one extreme an anarchist group bent on creating the "state of terror" of the title and a family of arms-smuggling Kurds, at the other touchingly naïve Judge Roban, back at his desk but ostracised by his slimy colleagues for previous abortive attempts at whistleblowing, yet determined to press on regardless out of principle.
Somewhat implausible as ever (but who cares?), driven, designer-scruffy Capitaine Laure Berthaud continues to rush about, hair escaping from its clip, T-shirt slipping off one shoulder, turning a blind eye as her male underlings beat up uncooperative suspects in the office, and screaming "Putain" on the frequent occasions when, having done an impressive job identifying a gang's rendezvous, they let the criminals escape. To be fair this is usually because they have insufficient back-up.
Also implausible yet entertaining is Pierre's continued working partnership with the seductive, talented yet unscrupulous Josephine, although at last we learn some reasons for her warped emotions. Pierre seems to be swapping one devil for another, in quitting the state legal service out of concern over its corruption only to take on as a client a notorious villain, against even Josephine's advice.
The dramatic final scenes avoid a run-of-the-mill "happy for everyone against the odds" ending. Although the key aspects of the conclusion are predictable, there are enough twists to continue the suspense to the last.
For a viewer dependent on sub-titles, the fast-moving plot requires total concentration, but the recap, "précédemment" opening each of the twelve episodes helps one to focus on the key points. Once again, I cannot imagine what the producers will pull out of the bag for what I believe is the final series, but am confident it will be good.
