In fairy-tales, witches always wear silly black hats and black cloaks, and they ride on broomsticks.
But this is not a fairy-tale. This is about REAL WITCHES. The most important thing you should know about real witches is this. Listen very carefully. Never forget what is coming next.
REAL WITCHES dress in ordinary clothes and look very much like ordinary woman. They live in ordinary houses and they work in ORDINARY JOBS.
That is why they are so hard to catch.
