Phil Smith – The Incredible Melting Man (Nel, 1978)
Blurb:
Three astronauts had returned safely from the Mars landing. Two were dead and Steve West was on the run.
On the run from the quarantine hospital which had been treating him … from the authorities who had to conceal his escape at all costs … from his friend Ted Nelson … and from the dreadful organism which had taken possession of his flesh, turning him into a fiendish nightmare but leaving his mind intact to cringe from the murderous horror he had become.
“What unearthly offspring would grow from the jelly that was once his friend?”
An outrageous rip off of The First Man In Space via Quatermass. Steve West, the “jelly” in question, brutally destroys a nurse and flees the hospital so that he can turn to sludge in peace. Since his exposure to whatever radiation it was that has poisoned his cells, he’s developed a taste for human flesh and blood (unfortunate for him but very rewarding for us) and roams the woods killing people and leaving pools of mucous everywhere.
Naturally, General Parry over at Houston doesn’t want a word of this to come out as “Nothing must interfere with the next phase of the programme”, so Dr. Nelson is ordered to find his friend and return him to the Hospital without anybody finding out that the psycho-killer is not only a blob of slime but … their astronaut.
