"Would that take much courage?" His smile was a little mocking; he was
thinking that a girl who would hurry that note to him, and would
personally see that it did not fail to reach him, would have the courage
for much more.

She did not reply directly. "I should have to explain, but I know you
won't tell. This is going to be my piece de resistance, my grand stunt.
I'm going to bring it off the last night." She stopped long enough for
Verrian to revise his resolution of going away with the fellows who were
leaving the middle of the week, and to decide on staying to the end.
"I am going to call it Seeing Ghosts."

"That's good," Verrian said, provisionally.

"Yes, I might say I was surprised at my thinking it up."

"That would be one form of modesty."

"Yes," she said, with a wan smile she had, "and then again it mightn't be
another." She went on, abruptly, "As many as like can take part in the
performance. It's to be given out, and distinctly understood beforehand,
that the ghost isn't a veridical phantom, but just an honest, made-up,
every-day spook. It may change its pose from time to time, or its
drapery, but the setting is to be always the same, and the people who
take their turns in seeing it are to be explicitly reassured, one after
another, that there's nothing in it, you know. The fun will be in seeing
how each one takes it, after they know what it really is."

"Then you're going to give us a study of temperaments."
