C.P. Snow 
Light and the Dark [EPUB ebook] 

A gifted young academic in 1930s England falls prey to a dangerous mindset in this novel by “a master craftsman” (The New York Times). Roy Calvert is young, well-liked, and financially secure. He is also a brilliant scholar at Cambridge, engaged in translating ancient documents related to the Manichaean heresy. Yet despite these advantages and successes, he is prone to an unpredictable, inexplicable melancholy that neither love nor work can seem to overcome. It will pull Roy into the orbit of a rising historical darkness—and leave his friend, Lewis Eliot, to witness the frightening struggle between Calvert and his demons . . .Praise for the Strangers and Brothers Novels “Mr. Snow has established himself . . . in an eminent and conspicuous position among contemporary English novelists.” —New Statesman
