long draught of beer, "I feel better.
Where's the next draw?"

The notebook lay on the table between them. Tuppence picked it up.

"Mrs. Vandemeyer," she read, "20 South Audley Mansions. Miss Wheeler, 43
Clapington Road, Battersea. She's a lady's maid, as far as I remember,
so probably won't be there, and, anyway, she's not likely."

"Then the Mayfair lady is clearly indicated as the first port of call."

"Tommy, I'm getting discouraged."

"Buck up, old bean. We always knew it was an outside chance. And,
anyway, we're only starting. If we draw a blank in London, there's a
fine tour of England, Ireland and Scotland before us."

"True," said Tuppence, her flagging spirits reviving. "And all expenses
paid! But, oh, Tommy, I do like things to happen quickly. So far,
adventure has succeeded adventure, but this morning has been dull as
dull."

"You must stifle this longing for vulgar sensation, Tuppence. Remember
that if Mr. Brown is all he is reported to be, it's a wonder that he has
not ere now done us to death. That's a good sentence, quite a literary

"You're really more conceited than I am--with less excuse! Ahem! But it
certainly is queer that Mr. Brown has not yet wreaked vengeance upon us.
(You see, I can do it too.) We pass on our way unscathed."

"Perhaps he doesn't think us worth bothering about," suggested the young
man simply.

Tuppence received the remark with great disfavour.

"How horrid you are, Tommy. Just as though we didn't count."

"Sorry, Tuppence. What I meant was that we work like moles in the dark,
and that he has no suspicion of our nefarious schemes. Ha ha!"

"Ha ha!" echoed Tuppence approvingly, as she rose.

South Audley Mansions was an imposing-looking block of flats just off
Park Lane. No. 20 was on the second floor.

Tommy had by this time the glibness born of practice. He rattled off
the formula to the elderly woman, looking more like a housekeeper than a
servant, who opened the door to him.

"Christian name?"

"Margaret."

Tommy spelt it, but the other interrupted him.

"No, G U E."

"Oh, Marguerite; French way, I see." He paused, then plunged boldly. "We
had her down as Rita Vandemeyer, but I suppose that's incorrect?"

"She's mostly called that, sir, but Marguerite's her name."

"Thank you. That's all. Good morning."

Hardly able to contain his excitement, Tommy hurried down the stairs.
Tuppence was waiting at the angle of the turn.

"You he
