- A WILY PUZZLE
In the diagram it will be seen that the prisoner's course is undoubtedly all
right until we get to B. Ifwe had been the prisoner, when we got to that point
we should have placed one foot at C, in the neighboring cell, and have said,
"As one foot has been in cell C we have undoubtedly entered it, and yet when
we withdraw that foot into B we do not enter B a second time, for the simple
reason that we have never left it since we first went in!"
