eight o'clock in
the evening
It was Florence Levasseur . Don Luis was for one moment amazed . Florence Levasseur here ! Florence , whom he had left in the train under Mazeroux 's supervision and for whom it was physically impossible to be back in Paris before eight o'clock in the evening ! Then , despite his bewilderment , he at once understood . Florence , knowing that she was being followed , had drawn them after her to the Gare Saint-Lazare and simply walked through the railway carriage , getting out on the other platform , while the worthy Mazeroux went on in the train to keep his eye on the traveller who was not there . But suddenly the full horror of the situation struck him .
