“Yes!”
Belle Braddon turned and pressed her hand on the wall.
Instantly a heavy iron door, decorated like the wall to which it was most cleverly matched, swung quickly open.
A four-foot passage was revealed, brick walled on two sides. At the farther end of it, some five feet away, a similar iron door had swung open, and beyond it was Flood’s private room, which Nick immediately recalled.
Belle Braddon raised her finger warningly, and led the way into the passage.
Nick followed her, wondering what he might expect in the adjoining house.
When both were in the passage Belle turned back and paused, whispering softly:
“Draw that door after you, please! Close it quietly.”
Nick turned to lay his hand on the door.
Like a flash Belle Braddon sprang into Flood’s private room and dashed her hand against the side wall.
