Esio Trot

This celebrated, splendidly matched author-illustrator team here present a 64-page love story that is equally sweet and silly. For years, Mr. Hoppy has leaned over his balcony rail to gaze longingly at Mrs. Silver, who lives one floor below him. But all of her attention and affection is showered upon her pet tortoise, Alfie. Although the creature seems content, his devoted owner is concerned because he has gained a mere three ounces in the 11 years she has owned him. When the distressed Mrs. Silver tells her neighbor that she will be his ``slave for life'' if he can find a way to make Alfie grow, the determined Mr. Hoppy devises an elaborate scheme to make her think the tortoise is growing. (Since tortoises, according to Mr. Hoppy, are backward creatures that ``can only understand words that are written backwards,'' his exhortation to the pet begins ``Esio Trot''--which is ``tortoise'' reversed.) It is a happy Hoppy who gets all the credit--and Mrs. Silver's hand. Adults and older children will appreciate Dahl's superior storytelling skills, and will chuckle at Blake's animated, cartoony drawings. But the book's length and subtle humor make it less suitable for beginning readers. All ages. (Oct.)
