Colorless Mr. Hatch--who works in a shoelace factory and eats a cheese and mustard sandwich for lunch every clay with, just occasionally, a prune--is jarred from his reserve by receiving a huge Valentine box of candy with a-card that says only, ""Somebody loves you."" Amazed, he samples it, shares it at work and, buoyed by his friendly reception, sympathetically helps several people out on the way home (e.g., he watches the newspaper stall so that its proprietor can take his cold to the doctor). He's soon baking brownies, hosting a neighborhood picnic, and reading to the local kids. Then the postman arrives with the news that the candy was delivered to the wrong address, putting poor Mr. Hatch into a funk; but his devoted new friends rally round to bring him back into their cheerful society. Told with warmth and a light touch, the story easily transcends its predictability. It's much enhanced by Yalowitz's mellow color-pencil illustrations. His unique elongated characters with their extra-tall heads are at once animated and serene; the smooth clarity of his scenes is enlivened with many amusing details. A charming book with a real plot, its amiable tone beautifully complemented by the intriguing illustrations.
