eight o'clock
It was really too tempting . The jet necklace , the toque with the autumn leaves , the old woman with the silver rosary : how could she resist their mysterious appeal and how could she refuse this opportunity of showing Rénine what she was capable of doing ? `` And then , after all , '' she said to herself , laughing , `` he 's summoning me to Paris . Now eight o'clock is dangerous to me at a spot three hundred miles from Paris , in that old deserted Château de Halingre , but nowhere else . The only clock that can strike the threatening hour is down there , under lock and key , a prisoner ! '' She reached Paris that evening . On the morning of the 5th she went out and bought a jet necklace , which she reduced to seventy-five beads , put on a blue gown and a toque with red leaves and , at four o'clock precisely , entered the church of Saint-Étienne-du-Mont .
