THE LONG GOODBYE (316 pp.)Raymond ChandlerHoughton M/ffl/n ($3).
CASINO ROYALE (176 pp.)Ian FlemingMocm/7/on ($2.75).
Good writing is a mystery to most mystery writers. But the border line between a good mystery and a good novel is occasionally crossed, and two new yarns get well over the border. In The Long Goodbye, Old Mystery Hand Raymond Chandler brings back his private eye, Philip Marlowe, for his first stint in more than four years. Casino Roy ale introduces a brand-new mystery writer, Briton Ian Fleming, and a hard-shelled British secret-service operative, James Bond, who should be prowling the international underground for some books to come.
