Amanda could stand it no longer. Before Elizabeth could stop her, she put her mouth up to the shutter and said in a low but firm and penetrating voice, "Miss Potts!"
There was a deathly silence within the room. Outside, Amanda stood tense, and Elizabeth began cautously to edge towards the boat - if they were going to run for it, she felt, she preferred a head start.
"Miss Potts," said Amanda again,"can you speak to me? It's me, Amanda-"
To their astonishment, the shutter was unbolted and pushed open and a small anxious face with glasses, surmounted by rather wispy grey hair, appeared.
