There was the sudden shrill of a police whistle but it was stopped after
one brief blast. As I turned the corner, I caught a fast backwards dig
at them. They were filing back into the hotel. I did not believe that
the policeman was part of the conspiracy, but I was willing to bet that
Walton was going to slip the policeman a box of fine cigars as a reward
for having helped them to get rid of a very embarrassing screwball.
