"Of course I will," he said boyishly, at once pleased with himself
and his sympathetic audience. "About five-thirty I happened to be
in the club. Medford was there, and as usual catering to Jackson,
when the latter was called to the 'phone. Naturally, I put two
and two together." He paused to more thoroughly enjoy the look of
utter mystification that hovered on the girl's countenance. It was
very apparent that this method of deduction through addition was
unsatisfying. "What Jackson said to Medford, on his return," the
young man continued, "I did not hear; but from the expression on
the listener's face I could have wagered that an invitation had been
extended and accepted. Oh, we boys have got it down fine! Garrison
is---"

"And who is Garrison?"

"Garrison is the head door man at the club. It's positively amazing
the number of telephone calls he receives every afternoon from
well-known society women!"

"What about? And what's that got to do with Mr. Medford taking me
in to dinner?"

"Just this: Suppose Mrs. Rowden..."

"Mrs. Rowden!" The girl was nonplussed.

"Yes--wants to find out who's in the club? She 'phones Garrison.
Instantly, after ascertaining which set--younger or older is wanted,
from a small card upon which he has written a few but choice names
of club members, he submits a name to her."
