seven o'clock in the evening
Ganimard at once went to the offices of the _ Turf _ and asked to see the list of subscribers . Going through the list , he jotted down the names and addresses of all those who lived anywhere near the Pont-Neuf and principally -- because Lupin had said so -- those on the left bank of the river . He then went back to the Criminal Investigation Department , took half a dozen men and packed them off with the necessary instructions . At seven o'clock in the evening , the last of these men returned and brought good news with him . A certain M. Prévailles , a subscriber to the _ Turf _ , occupied an entresol flat on the Quai des Augustins . On the previous evening , he left his place , wearing a fur coat , took his letters and his paper , the _ Turf Illustré _ , from the porter 's wife , walked away and returned home at midnight . This M. Prévailles wore a single eyeglass .
