     Outside her shabby cottage, old Mrs. Tailor was hanging out laundry on a wire line, unaware that

some children lay hidden in the leaves of a nearby tree watching her every move. They were determined

to find out if she really was a witch.

     They watched as she took a broomstick to clean the dirt from her stone steps. But, much to their

disappointment, she did not mount the broomstick and take flight. Suddenly, the old lady's work was

interrupted by the cackling of her hen-a signal that an egg had been laid in the warm nest on top of the

haystack.

     The old broomstick was put aside as she hobbled off towards the haystack followed by Sooty, a

black cat she had rescued from a fox trap some time back. With only three legs, it was hard for Sooty

to keep up with the old lady. The cat provided proof-the children were sure that only a witch could

own a black cat with three legs.

     There, standing on a wooden box, was Mrs. Tailor, stretching out to gather her precious egg. Taking

the egg in one of her hands, she began to climb down when, without warning, the box broke and the

old lady fell.

     "We have to got and help her," whispered Amy.

     "What if it is a trick?" replied Ben.

     "Don't be silly, Ben. If she were a witch, she would have turned us into frogs already," reasoned

Meg. "Come on Amy, let's go." The girls climbed down the tree and ran all the way to the haystack.

     Approaching carefully, they could see a wound on the old lady's face. She had knocked her head

on a stone and her ankle was definitely broken. "Go and get Dad," Amy yelled to her brother. "Tell him

about the accident."

     The boys did not need another excuse to leave. They ran as fast as they could for help, hoping that

Mrs. Tailor would not wake and turn the girls into frogs.
