Maigret et son Mort

From which I have learned about a whole new sport 'courses cyclists derrière moto'.

It took a minute or so to track down what this meant, with the usually helpful linguee site not being helpful at all on this occasion. But from 'races cycles motorcycles france', google took me to reference 1, from where I quickly got to reference 2, where I learned that racing cycles right behind a motorcycle, both to provide pacing and to provide slipstream, used to be a popular sport, particularly in Germany between the wars, but also in France and the US. Maybe six pairs to a race, with the amount of rules varying from place to place, from race to race.

Big spectator sport in vélodromes, maybe because it was both fast and dangerous.

Still goes on, as can be seen from reference 3, but I have never heard of it before, so maybe not such a big sport these days. Stopped for the duration of the first world war, but carried on through the second.
