'Denfert-Rochereau,' cried the conductor. Mathieu rose and got out : he turned down the Rue Froidevaux. He was tired and nervous, he kept on seeing a suitcase at the far end of a dark room, and in the suitcase some soft and odorous bank-notes; with a sense of something like remorse. 'Ah, I ought to have taken them.'

The Age Of Reason, p.300

He laid his elbows on the balcony, and yawned. In the street below a man was walking quietly along: he stopped at the corner of Rue Huyghens and Rue Froidevaux, raised his head and looked at the sky: it was Daniel.

Rue Hughens being on the northern side of the Montparnasse cemetery, Froidevaux on the southern.
