They made a quick search and went all over the hotel.
They made inquiries of bell-boys and other attaches.

It convinced them that they were truly up against a hard game.
The trio seemed possessed of a supernatural faculty for making themselves invisible at will.
Completely mystified, the Bradys sat down in the hotel lobby and tried to think.

It was easy to understand their game.
