"Come up into the cage, Sir John," said Edward Henry. "You'll get a still better view. Rather fine, isn't it, even from here?"

He climbed up into the cage, and helped Sir John to climb.

And, standing there in the immediate silence, Sir John murmured with emotion:

"We are alone with London!"

Edward Henry thought:

"Cuckoo!"

They heard footsteps resounding on loose planks in a distant corner.

"Who's there?" Edward Henry called.

"Only me!" replied a voice. "Nobody takes any notice of me!"

"Who is it?" muttered Sir John.
