"Anyone removing that board has got to put it back to match that line," said Oakes, "and that with a board is practically impossible where nailing has been done. Now for the exit that opens near the well." We went back through the cellar hall and found at the east end a door ajar. It did not lock, and was hung on rusty hinges. Beyond was a dark passage. "Where does this lead, Mike?" [Pg 119] [Pg 119] "To the opening by the well, sorr." "How do you know?"
