On a dark evening in 1824, a lady is offered a ride home in the carriage of a dark and mysterious stranger and a boy is conceived, to the strains of Beethoven's brand-new setting to the Ode to Joy. Groomed from childhood to become a perfect British hero, young Edward Alton Bell-Fairfax proceeds uncertainly through public school, a career in the navy, mutiny and court-martial before discovering his true place in life. There is, in Whitehall, a comfortable and slightly shabby club called Redking's. Downstairs from Redking's, however, is concealed the London headquarters of the Gentlemen's Speculative Society... a centuries-old fraternity devoted to the development of what its members call Technologia. Their goal is to bring about a Utopian paradise of science, through the manipulation of men and governments. Edward, as one of their agents, sets off on an odyssey across 19th-century Europe, encountering on the way flying machines, self-propelled carriages, and an Underground Galvanic Railway... and learns that the Society, in its various disguises, is everywhere.
