This new addition to the series for beginning readers was adapted from THE LITTLES AND THE GREAT HALLOWEEN SCARE (Scholastic 1975).
Every Halloween, Tom and Lucy try to think up a trick that will really scare their parents -- but nothing works. This year, the two children are sure they'll find something scary in the Biggs' attic. And they do -- a hairy spider! Lucy gets caught in the spider's web, but Tom manages to fend off the insect. They both escape to the Biggs' kitchen, where they get trapped for hours inside a jack-o-lantern. When they finally get back to their apartment, they find two very frightened parents. Success is bittersweet for Tom and Lucy, who promise not to do anything quite that scary again.
