Fleischman's favorite folk-motif, the tell-tale object, is used with panache in this tale of Finzel the fortune-teller--who, in true Fools of Chelm tradition (the jacket says it, but it's so), can see a person's past or future in a lemon or a walnut. . . but can't see well enough to tell whose lemon is whose. Specifically, he mixes up the lemon and the walnut, and the lettuce, of young simpleton Pavel and elderly ailing Mashka, and has Pavel convinced he's near death. When Pavers wily brother Osip catches on to Finzel's blindness, he hatches a scheme to steal Finzel's money--by having Finzel read a poppy plucked from his own window box. . . and telling him where he (Osip) keeps his (Finzel's) money. In true Chelm tradition, too, Finzel outwits Osip by mistake--also making nothing more of him, as a thief, "than a mouse." Sewall's chunky figures are immediately recognizable types, but with character and individuality. A droll and shapely little book--on a par, in its way, with Graven Images.
