THE CURRENTS OF SPACE

Panther SF paperback, 1973 reprint. Cover painting by Chris Foss.

"DOOMED PLANET 

They called him 'Crazy Rik' - but only he knew that they planet was doomed with all its people. The only key to the vital information that could save it was locked in the subconscious memory of this strange, child-minded man...a memory obliterated by a Psychic Probe! 

Caught in a galactic web of intrigue, Rik struggled courageously with his own blasted mind and an unknown enemy in a desperate and one-sided race with time... 

Here is a nova-bright novel of tension and adventure by the acknowledged High Master of today's science fiction, Isaac Asimov."

I'm greedy - here's another book I unwittingly bought two copies of. The 1973 one with the Chris Foss cover (which I didn't think I still had) was/is my reading copy, the 1967 edition is unbelievably free from wear and is unread.
