Odd's fish, m'dear, you must read this novel. Wildly popular since his debut in 1903, the man known as the Scarlet Pimpernel is a foppy English lord by day and a daring genius by night. The time is the French Revolution, specifically Robespierre's Reign of Terror, and in Paris the aristos are going to the guillotine by the hundreds. One man, and one man only, seems poised to save their lives…"is he from heaven, or is he from hell, that damned elusive pimpernel?" Ages 12 and up.  (FRN363, $9.95)
