"Has what it takes: suspense, humor, and intriguing clues. A book that's as much fun as Halloween itself." —School Library Journal

While trick-or-treating on Halloween night, Helen and her dog Martha (begrudgingly dressed as a cat) walk into a very unusual supermarket. One for witches and cats only! What will happen if the manager realizes the truth about them? This whimsical story by Susan Meddaugh is the first about Martha from PBS's Martha Speaks, before she got her paws on the alphabet soup that gave her the gift of gab.

This new 8" x 8" edition features a shiny foil cover and a sheet of stickers!
