L'Art de Plongée - Les Enquêtes Auto de Margot

This week I'm showcasing some beautiful artwork done in the Ligne Claire (Clear Line) style pioneered by TinTin creator Hergé.

Writer/artist Olivier Marin combines a love of Ligne Claire and classic cars in his series Les Enquêtes Auto de Margot. The series begins in 1959 where Margot is an aspiring journalist trying to make a career at a male-dominated motoring magazine. The sequence I'm featuring comes from the fourth volume, Le Pilote aux Deux Visages. Marin shares the art chores with Callixte (Damien Callixte Schmitz) who is also the colourist. (Click for larger images.)

The story opens in Tuscany in 1962 where Margot is honeymooning with her husband Louis. They discover a door and a wheel from a Fiat 500 washed up on the beach. They find out that there had been an accident during a race and a car had gone over a cliff. At first the driver was reported to have been killed but later it was claimed that he had survived but with severe injuries. Margot tracks down the disfigured, wheelchair-bound driver but is shocked to see him leave the wheelchair and walk about. Determined to find out more, she decides to go diving and look for the Fiat, much to the dismay of Louis.

As the book is still on sale I'm not going to give away any more of the story. If you want to find out what happens you'll have to track down a copy (and learn French if necessary!).

The diving gear used is historically accurate. Margot is using the classic Mistral regulator and we can see the name in the last panel featured.

The mystery diver has the three-tank set-up often used by Cousteau and his team. I was particularly interested to see that Margot's kit is equipped with a J valve.

Like a lot of divers, I learnt about these when I did my Open Water course but have never used one. The J valve shut off when the tank reached 500psi (34 bar) of air and the diver would pull down on the lever to re-open the valve. This was the signal to end the dive and head for the surface. Modern pressure gauges have rendered the J valve obsolete.


  1. Great post and nice research. The artwork is incredible with lots of attention to details. Of course Margot is easy to look at too. Thanks for the explanation of how the J-Valve works.

  2. One common mistake again. The guy with the three bottle setup says "plus d'oxygene". wich means "no oxygen anymore". If he would be diving at that depth with oxygen he would be dead. For the rest an excellent classic BD "Bande Dessinee" with some fine details to the divinggear but also the boat and the car.
