Philip Rush keeps action stirring, suspense alive and characterization three dimensional in this tale of a vainglorious young man, Lambert Simnel, whose vanity makes him the pawn of an unscrupulous group headed by a villainous priest, William Symonds. Lambert swears his sister Blanche to secrecy and reveals their plan for him to impersonate the imprisoned Earl of Warwick in order eventually to control the British throne. Blanche weighs loyalty to King and brother and follows a course to aid them both with the guidance of her confessor. Her pluck brings high adventure with a gallant comrade, Richard Carvel. This is a vivid account of the War of Roses, with characterization kept more important than battles. It seemed to this reader rather like an enlargement of a choice section in a rare medieval tapestry.
