eight o'clock
* * * * * Christophe 's first thought , when he awoke the day after the Roussins ' party , was for Olivier Jeannin . At once he felt an irresistible longing to see him again . He got up and went out . It was not yet eight o'clock . It was a heavy and rather oppressive morning . An April day before its time : stormy clouds were hovering over Paris . Olivier lived below the hill of Sainte-Geneviève , in a little street near the _ Jardin des Plantes _ .
