I love my job because among other things it allows me to travel to places like Paris. Looking around bookshops in the French capital is always a very enjoyable activity, a little bit of a detective work in spotting some of our titles on the shelves. And here they were, in Le Carrousel, copies of our best-selling 30 Second series.

If the word best-selling sounds vague, the generous contribution by our statistically minded colleague is bound to put everything in place, in less than 30 Seconds: Nine titles, 20 languages, over half a million copies sold worldwide, one third of which in French language. Plenty of choice for everyone. Take your pick of title and language. Published in France by Guy Trédaniel Editeur and in French speaking Canada by Les Éditions Hurtubise
