Why did Arnold Armstrong come back after he had left the house the night he was killed?
No answer. Was it on the mission Louise had mentioned?
Who admitted him?
Gertrude said she had locked the east entry. There was no key on the dead man or in the door. He must have been admitted from within.
Who had been locked in the clothes chute?
Some one unfamiliar with the house, evidently. Only two people missing from the household, Rosie and Gertrude. Rosie had been at the lodge. Therefore—but was it Gertrude? Might it not have been the mysterious intruder again?
Who had accosted Rosie on the drive?
Again—perhaps the nightly visitor. It seemed more likely some one who suspected a secret at the lodge. Was Louise under surveillance?
Who had passed Louise on the circular staircase?
Could it have been Thomas? The key to the east entry made this a possibility. But why was he there, if it were indeed he?
