"As I was talking to Miss Langton at the door of her room (No.
2) on my way to dress for dinner, a double bang on the door came
from the inside of room No. 1, which was the one Captain B----
had occupied, and where he had heard nothing. At the same moment
Miss Langton called out that there had been a bang on the door
between her room and No. 1. For a moment I hesitated to go in,
but a housemaid came down the corridor at that moment to see
what the noise was she had heard, and we investigated together,
but to no purpose."
