In the incinerator, at the bakery--where in a city project would a monster hide? Martin, Cookie and their friend Frankie hunt monsters on Halloween with a pillowcase trap; they catch one in an empty schoolyard pipe, but when let out of the bag it's only a cat. The six-child Negro family and white super, baker, and friend are blandly (but unobjectionably) portrayed; the colored pages, alternating with black and white, are, in magenta and orange, more frightful than any monster. A pint-sized story for pint-sized Halloween terrors, with enough adventurous spirit to please the action-raised TViewer.
