During 1966 to 1972 Michael Critchton wrote a series of thrillers under the pseudonym of “John Lange.” Critchton was learning how to write and finally, with The Andromeda Strain and The Terminal Man, Critchton became a best-selling writer under his own name. HARD CASE recently reprinted the John Lange novels. I read them when they were first published (I didn’t know at the time they were written by Critchton). I found them entertaining. You will too.
