A partial ISBN appears on the spine '449-01989' followed by the price '-095'. Converting this to an ISBN 0-449-01989-6 does not find any catalog entries under it.
Originally published under the David St. John name, this paperback edition gives the Canonical Name (E. Howard Hunt), followed by "Writing as David St. John" on both the cover and the title page. Presumably this was to leverage his Watergate conspirator status of the time.
