"TOMMY, old thing!"

"Tuppence, old bean!"

The two young people greeted each other affectionately, and momentarily blocked the Dover Street Tube exit in doing so. The adjective "old" was misleading. Their united ages would certainly not have totalled forty–five.

"Not seen you for simply centuries," continued the young man. "Where are you off to? Come and chew a bun with me. We're getting a bit unpopular here—blocking the gangway as it were. Let's get out of it."

The girl assenting, they started walking down Dover Street towards Piccadilly.

"Now then," said Tommy, "where shall we go?"

The very faint anxiety which underlay his tone did not escape the astute ears of Miss Prudence Cowley, known to her intimate friends for some mysterious reason as "Tuppence." She pounced at once.

"Tommy, you're stony!"

"Not a bit of it," declared Tommy unconvincingly. "Rolling in cash."

"You always were a shocking liar," said Tuppence severely, "though you did once persuade Sister Greenbank that the doctor had ordered you beer as a tonic, but forgotten to write it on the chart. Do you remember?"

Tommy chuckled.

"I should think I did! Wasn't the old cat in a rage when she found out? Not that she was a bad sort really, old Mother Greenbank! Good old hospital—demobbed like everything else, I suppose?"

Tuppence sighed.
