There’s just one word this week: une perquisition, which means search. It’s often used in a legal context, such as in this article about the Bettencourt affair. Perquisition is often part of the phrase un mandat de perquisition, meaning search warrant.
I’ve encountered this word a few times this month, since I’ve also been reading some French mystery novels. My review of L’Ami d’Enfance de Maigret, by Georges Simenon, should be up soon. I’ve also been reading (very slowly) an ebook edition of Le Nº 13 de la rue Marlot, by René de Pont-Jest.
