Maigret and the Wine Merchant: Inspector Maigret, Book 71 (Unabridged‪)‬

'Maigret had never been comfortable in certain circles, among the wealthy bourgeoisie where he felt clumsy and awkward.... Built like a labourer, Oscar Chabut had hauled himself up into this little world through sheer hard work and, to convince himself that he was accepted, he felt the need to sleep with most of the women.'

When a wealthy wine merchant is shot in a Paris street, Maigret must investigate a long list of the ruthless businessman's enemies before he can get to the sad truth of the affair.
