Journalist and writer, with a specialization in mathematical logic, deputy director of the Association Valaisanne des Entrepreneurs (AVE), Chiara Meichtry-Gonet is at the crossroads of several paths... or rails, one might say. In autumn 2020, she published her second novel Mathilde-sous-Gare with Bernard Campiche. It was an opportunity for me to meet her and discuss her singular profile and her vivid, disturbing world, during a trip by train and elsewhere.
