For the second time (see Plain Jane, 1962, p. 1014, J-296) the author has set an unusual adventure story against the background of the Civil War in England in 651. After his father is shot by the Royalists for being a traitor, embittered young Nicholas leaves home to join the Royalists' forces. A few years later, he is forced by circumstance to return home with two friends and seek refuge. When the youths unknowingly keep close quarters with a Round Head sympathizer, the plot thickens, and continues to thicken until the end. The author maintains a tone of intensity throughout; the characters-- major and minor-- are well developed, although the children at times seem almost too mature for their years. A welcome historical novel-- partially owing to the author's reliance upon a distinctive period of history.
