“Across the water,” was echoed in a low, deep murmur by every one but Frank.

Then hand ceased to clasp hand, people began to leave, and Mr Selby went quickly to the other end of the room.

“All over,” said Andrew, in a quick whisper. “Now then off, or we shall get into trouble for being late.”

“Yes, let’s go,” said Frank, in a bewildered way; and he went downstairs with his companion, and out into the cool, pleasant night air of the street.

“We shall have to walk,” said Andrew, “so step out.”

Frank obeyed in silence, and nothing more was said till, without thinking of where they were, they saw Temple Bar before them.

“What did they mean by that?” said Frank suddenly.

“By what?”

“Joining hands together and saying ‘Across the water.’”

“Oh, nothing. A way of saying good-bye if you live in Surrey.”
