The Terror: The Return of Dr. Palfrey

Published three years after #21, The Drought, a long break in this series.

• Revised for the 1966 Walker edition(?) (almost certainly revised by the author, if at all)
• The series bibliography at SFE3 reports some revision ("rev"), which may be expected because this was the first of more than 20 Dr. Palfrey stories published by Walker and Company for the US market.
• Library of Congress record {{LCCN|66016921}} does not report any revision ("rev. ed." usually) and does report 191 pages, which matches the 1962 original. The same is true of library records found October 2018 at WorldCat.
