Note: Some sources, e.g. "The Keith Laumer Website" (http://www.keithlaumer.com/biography.htm) list "Rafe Bernard" as a Keith Laumer pseudonym. Other sources disagree. According to http://en.wikipedia.org/wiki/Keith_Laumer (as of 2010-10-13): "Army of the Undead by-lined Rafe Bernard (1967) is often mistakenly attributed to Laumer because it is the 3rd entry in the Pyramid Books Invaders novel series as published in the US, but in fact Bernard (a name which may be a pseudonym, but not for Laumer) was one of the two British authors commissioned by Corgi Books in the UK to pen original novels based on the TV show (the other was Peter Leslie). The book appeared as the third title in Corgi's UK line as The Halo Highway. Evidence seems to indicate a reciprocal reprint deal Pyramid worked out with Corgi for use of a single title, since only the Bernard book, but not the Peter Leslie ones, saw print in the States; while only Laumer's first Invaders title, but not his second, saw print in the UK. Bernard's by-line exists on one other science fiction title, The Wheel in the Sky published as a UK hardcover in 1954 and as a UK paperback by Ward Lock in 1955. (Verification can be found in Kurt Peer's book TV Tie-Ins (1967, Neptune Publishing and later TV Books) and in the Rafe Bernard book itself, written in stilted, purple, overwrought prose that bears not even slight resemblance to Laumer's style, plus the British author's inadequate handling of American rhythms and colloquialism, which were a hallmark of Laumer's prose. Additionally, Bernard's The Wheel in the Sky, never cited as a Laumer title, can be found listed at antiquarian book sites like alibris.)"
