midnight
Was it an accomplice who had come back to investigate ? Were they to suppose that the leader of the gang had not left the cloisters or the neighborhood of the cloisters ? That night , Ganimard openly sent the squad of gendarmes to the farm and posted himself and Folenfant outside the walls , near the little door . A little before midnight , a person passed out of the wood , slipped between them , went through the door and entered the park . For three hours , they saw him wander from side to side across the ruins , stooping , climbing up the old pillars , sometimes remaining for long minutes without moving . Then he went back to the door and again passed between the two inspectors . Ganimard caught him by the collar , while Folenfant seized him round the body .
