HUNTING GHOSTS
In his search for the medium of the leak to the enemy Bouchard had studied every detail of the Galland premises and also of the ruins of the castle, with the exception of one feature mentioned in the regular staff records, prepared before the war, in the course of their minute description of the architecture of buildings which were accessible to the spies of the Grays.

"What an idea! That musty, horrible, damp tunnel!" she exclaimed, shuddering. "I never think of it without thinking of ghosts!"
