“Shall we get on our things and slip down to the beach?” said Mike so excited that he could hardly stand still.

“Yes,” said Jack. “Peggy, wake Nora. There’s no hurry, because if that light has only just shone out of the tower, it will take some time for the boat to get round to Spiggy Holes. We’ve plenty of time to dress properly.”

Peggy flew down the winding staircase to tell Nora, who was still sleeping soundly. Peggy shook her, and Nora woke up in a hurry.

“Nora! The light’s in the tower! Hurry and get dressed, because we’re all going to creep down to the beach and hide in a cave to watch,” cried Peggy. Nora almost fell out of bed in her excitement. They put on their clothes in the dark, for Jack had forbidden lights of any sort in their tower, in case they should be seen from the Old House.

“If we can see their light, they could see ours,” said Jack.

“True, Captain!” said Mike and dressed himself at top speed. He put on both his stockings inside out, and buttoned his coat up wrong - but who minded?

They were all ready in five minutes. Jack took his torch and gave one to Peggy for the girls. They all crept down the staircase, out of the little tower door, and down the garden path, where the smell of honeysuckle came to them.

“Nora’s got on her bedroom slippers,” said Peggy, with a giggle. “She couldn’t find her others.”

“Sh!” said Jack sharply. “Other people may be about, remember. We mustn’t be seen or heard.”

They went as quietly as they could down the rocky path to the beach. The tide was half in and half out. The moon swam out from behind a cloud and lighted up the shore for the children. Jack stopped and looked out over the sea.
