Tandem: French Mystery Series Set In Montpellier

The French mystery series, Tandem, is set in Montpellier, France

After divorce, the relationship between a husband and wife can be tricky, especially when kids are involved.

In the French mystery series Tandem, Commander Lea Soler (played by Astrid Veillon) and Captain Paul Marchal (Stéphane Blancafort) have been divorced for ten years.

They share custody and co-parent two teenagers, Thomas (Titouan Laporte) and his sister, Alice (Sarah Cheyenne-Santoni), both of whom suffer the usual angst of adolescence.

At the start of the series, Lea, who had been living and working in Lyon during the divorce, has just returned to Montpellier in the south of France to head up the investigation team.

Paul has no idea how his ex- landed in his domain, and he now winds up rather uncomfortably as her subordinate.

Although both are brilliant detectives and doting parents, their styles are polar opposites.

Lea is detailed, methodical, and controlling in her approach to work and parenting; Paul is relaxed and laissez-faire, relying on his intuition and impulse. She’s intense; he’s laid-back. This sets the scene for them to view everything from different perspectives.

There seems always to be a push and pull between the couple.

They share a history, a family, and a love of their work but get on each other’s nerves. French TV pundits have described the relationship as one of cat and mouse.

Why is the series called Tandem?

I can only speculate.

One can’t be sure what creator Jérémie Marcus had in mind when he developed the series, but my guess would be that it refers to the couple working together as partners in tandem as they simultaneously juggle demanding careers and parenting responsibilities.

The couple’s different personalities set the scene for an unending series of personal and professional conflicts that always seem to work out in the end, especially when they combine their efforts.

What are the episodes like?

Each episode is less than an hour long, and they need not necessarily be watched sequentially (the mysteries are solved in each episode, although the personal relationships of the detectives and their family evolve over the series).

The outcomes are unpredictable, making these true mysteries, although the pattern of episodes is pretty formulaic.

  • The stage is set even before the opening credits. A passerby finds a victim (usually in an unlikely place), and the police are called to investigate the murder. 
  • Long-legged and very attractive, Lea gets a call on her cellphone, responds to the call, arrives at the scene dressed in jeans, a v-neck tee shirt (usually tucked into the waistband of her pants), and a jacket, and assigns tasks to various team members.
  • As the story unfolds, the team pursues different leads through interviews with the victim’s family, friends, and associates. 
  • Someone back at the station is simultaneously checking databases to get more background information on suspects, sometimes interviewing people in the field.
  • A coroner (pathologist) at the morgue, Franck Marvaud (played by Francois-Dominique Blin), examines the victim to ascertain the time and cause of death. (BTW, he always seems to be smitten with Lea.)
  • Paul Marchal does sleuthing without waiting for instructions from his boss and ex-, Lea Soler. While this upsets her, she recognizes that he has good instincts. He is also quite attractive and athletic.
  • There are interludes when school or social problems occur with the kids at home that need to be resolved by one or two of these busy parents.
  • Questioning often takes place one-on-one in an interview room at the police station, which has a one-way camera so someone else on the team can watch what’s going on.
  • Almost every character appears to be a likely suspect (a testimony to the excellent writing). 
  • The murder case eventually cracks because of the combined intelligence and diligence of Lea and Paul, with the help of their team. 

Where was Tandem filmed?

Whereas the French mystery series Murder In takes viewers on a sprint across the country—each episode taking place in a different city, town, or village—the Tandem mysteries offer a deep dive into the culture of one French city, Montpellier, and its surroundings, its people and places.

As opposed to being on a high-speed train, the viewer watching this series will feel something akin to the riches of slow travel.

The episodes take place in actual locations. To name just a few locales, the backdrop for one episode is the city’s modern aquarium; another is its historic astronomy laboratory; another, the medical school at the University of Montpellier (which houses the oldest medical school in continuous operation); and another at the vineyards at Pic Sant Loup in the Languedoc wine appellation.

It was a thrill to see the actual interior of the Opera Comedie, the Italianate opera house in Montpellier that opened in 1888, and to learn in another mystery surrounding a perfumer’s death that Montpellier was France’s perfume capital before Grasse. An episode in Season 3 takes place in the Port-Camargue, the largest marina in Europe.

One fascinating episode concerns a death at a retreat of the Compagnons du Devoir. It sent me scurrying to Wikipedia to learn more about the organization and whether it really existed.

Since the Middle Ages, upcoming craftsmen and artists have been mentored in a community where they live in a house known as a cayenne and are managed by a mere who looks after them. Lo and behold, I learned that the group currently exists in 49 countries over five continents.

For those who haven’t been there, these episodes whet an armchair traveler’s desire to visit and learn more about Montpellier—When I got to the beginning of Season 2, I was already eager to plan a visit.

The series is beautifully filmed and extremely well-acted with an ensemble cast that includes Nelly Lawson (as Lieutenant Camille Barbier) and Pierick Tournier (as Erwan Lebellec), the two other major investigators on the team during the first two seasons. 

Unlike some other mysteries, this one has no violence (the murders seem to have happened prior to each episode). The Marchals have the chemistry of a real family, still reeling from the marital breakup.

Each episode of this easy-to-watch, binge-worthy series is infused with laugh-out-loud subtle humor to lighten the darkness. 

How many seasons of Tandem are there?

Tandem (sometimes called In Tandem) was first aired on the French public television channel France 3, in March 2016.

Due to its popularity in France (some episodes exceeding five million viewers), the show aired for 7 seasons. IMBD lists and describes each of the episodes in the series.

Where to watch Tandem:

In French with English subtitles, Seasons 1 through 6 of Tandem are streaming on Mhz Choice. There are twelve episodes in each season.

There are seven seasons of Tandem. Season 7, the final season, began airing on March 19, 2024, with two new episodes released in each successive week. The finale aired on April 23, 2024. The clever ending wrapped up a lot of answered questions but left me sad that the series was over.
