In the days before Eye of the Needle and international publishing fame, Follett published this novel under a pseudonym, Zachary Stone. Once his fame was achieved it was brought to the US and published by Morrow. Note that Morrow used the standard First U.S. Edition slug and number line down to ‘1’, whereas until 1973 their first editions were almost always identified by No Additional Printing. The jacket here is fairly sturdy with shelfwear being the most common defect.
