The plague of Demons was the first and second part of an IF Science fiction magazine story by Kieth Laumer from 1964, the first half appeared but I never found IF Science fiction mag following that one. There are several other stories in this book.
I followed Kieth Laumers Bio on the web which only recently led me to the second part and this book.
The original story serialised was called 'The Hounds of Hell' in If magazine(nov-Dec.,1964) as I said I waited all this time to read the conclusion but I was not disapointed.
