"What possessed her to go to the sub-cellar?" asked Foster.
"Probably a demon of unrest, or she may have had some message to leave for Heinrich," suggested Miller. "When he grappled with her in the dark she undoubtedly thought him a detective and dared not call out for fear of disclosing her identity. Probably she thought Heinrich out of the house, and never dreamed of his attacking her."
"And Heinrich mistook her for me." Julie's eyes glowed. "The hand of God! But, monsieur, why did you advise that I stay away from mademoiselle, and take me to that dreadful house?"
"Because, Julie, you were hysterical, and I feared if interviewed, you might make some statement in all good faith which would do Miss Kathleen irreparable injury. I also believed that your absence would serve to divert suspicion until I had a chance to find the real criminal; I met you before the inquest, and did not realize that your disappearance could be used to militate against Miss Kathleen. As for Mrs. Robinson"—he laughed slightly—"she keeps a private sanitarium, but just now has no patients. You were perfectly safe there, and I had Connor detail an operative to see that Heinrich did not torment you."
"What will become of Baron von Fincke?"
"Chief Connor and the State Department will handle his case. Connor told me he found the Baron's next door neighbor—a man named Frank Lutz…."
"Mercy, his wife's a member of the Sisters in Unity!" ejaculated
Miss Kiametia.
"Lutz has a complete wireless transmitting station," went on Miller. "He was stunned by his arrest, and attempted suicide; Connor believes he can induce him to tell the locations of the other relay stations. Lutz had the wireless antennae strung along the ceilings in the upper corridors of his house. He declares they have just perfected a method to overcome static interference."
"And what about Heinrich?" asked Julie anxiously. "Will he escape?"
"No, he will undoubtedly pay the penalty of his crime; Mitchell took him in charge. Coroner Penfield was here a short time ago," added Miller, turning to Miss Kiametia. "He assisted us to take Mrs. Whitney to her bedroom; I left Rosa, the cook, there."
