Prasville had sent his seconds to Daubrecq on the same day ; but Daubrecq refused to fight . A little while later , Prasville was appointed secretary-general . `` Very odd , very odd , '' said Lupin , who remained plunged in thought , while continuing to observe Prasville 's movements . At seven o'clock Prasville 's group of men moved away a few yards , in the direction of the Avenue Henri-Martin . The door of a small garden on the right of the house opened and Daubrecq appeared . The two detectives followed close behind him and , when he took the Rue-Taitbout train , jumped on after him . Prasville at once walked across the square and rang the bell .
