Lépic:Lacroix and the blind bookseller

It's not just tourists who love the bouquinistes, whose green folding boxes full of books adorn the banks of the Seine in Paris. Commissaire Lacroix also takes advantage of the spring weather to stroll along the stalls. But does the old man with the dark glasses have to recommend a Maigret novel of all things - when everyone knows that Lacroix doesn't like his nickname? Only later does he realise that it was the famous blind bookseller Hugo, who can recognise his customers' literary preferences simply by the sound of their footsteps. A little ashamed, Lacroix returns to the police station, where the head of the criminal investigation department is waiting for him: a young man - also a bouquiniste - has been recovered dead from the Seine, and his girlfriend is convinced that a crime has been committed.
