Chapter 1

"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?"

"Oh, Tommy!"

"No, old thing, not in riotous dissipation. No such luck! The cost of living--ordinary plain, or garden living nowadays is, I assure you, if you do not know----"

"My dear child," interrupted Tuppence, "there is nothing I do not know about the cost of living. Here we are at Lyons', and we will each of us pay for our own. That's it!" And Tuppence led the way upstairs.

The place was full, and they wandered about looking for a table, catching odds and ends of conversation as they did so.

"And--do you know, she sat down and cried when I told her she couldn't have the flat after all." "It was simply a bargain, my dear! Just like the one Mabel Lewis brought from Paris----"

"Funny scraps one does overhear," murmured Tommy. "I passed two Johnnies in the street to-day talking about some one called Jane Finn. Did you ever hear such a name?"

But at that moment two elderly ladies rose and collected parcels, and Tuppence deftly ensconced herself in one of the vacant seats.

Tommy ordered tea and buns. Tuppence ordered tea and buttered toast.

"And mind the tea comes in separate teapots," she added severely.

Tommy sat down opposite her. His bared head revealed a shock of exquisitely slicked-back red hair. His face was pleasantly ugly--nondescript, yet unmistakably the face of a
