"My plan is this," Tuppence went on calmly, "I'll go alone
to-morrow. I'll put him off again like I did to-day. It doesn't

"Or even longer!"

"You'll hang about outside. When I come out I shan't speak to
you in case he's watching. But I'll take up my stand somewhere

handkerchief or something, and off you go!"

"Off I go where?"

"Sort of thing one reads about in books. I somehow feel that in
real life one will feel a bit of an ass standing in the street
for hours with nothing to do. People will wonder what I'm up
to."

"Not in the city. Every one's in such a hurry. Probably no one
will even notice you at all."

"That's the second time you've made that sort of remark. Never
mind, I forgive you. Anyway, it will be rather a lark. What are
you doing this afternoon?"
