HH: "There are many reasons why writers use pen names - and most of the reasons are legitimate. A writer may have two stories in a single issue of a magazine, or write different sorts of stories each of which is identified with a pen name, or may just be ashamed to have his worse stuff appear under his real name. Another reason is conflict of interest. One of the editors of this magazine was, for a number of years, a correspondent for a medical newspaper. From this work he extracted at least one novel which will be familiar to Impulse readers (Plague From Space) and the background material for a series of stories more than slightly inimical towards the more stuffy aspects of the medical profession. To prevent a conflict of interests the stories were published under the name of "Hank Dempsey."

"Now it can be told. The connection with the medical journal has been severed and the real name can be revealed at last. And with the author's name the latest story in the chronicle of that rather unusual organisation, CWACC."
