Mme la duchesse est horriblement inquiète : un jour entier elle vous a cru mort abandonné dans quelque île du Pô ; je vais lui expédier un courrier à l’instant même.
The Signora Duchessa is terribly upset: for a whole day she thought you were dead, and had been left lying on some island in the Po; I must go and send off a messenger to her this very instant.
