A scientist plunged a kitchen knife into his colleague as he was fed up with the man telling him the endings of books, say investigators.

Sergey Savitsky, 55, and Oleg Beloguzov, 52, would pass the lonely hours during four harsh years together in a remote outpost in Antarctica by reading.

However Savitsky became angry after Beloguzov kept telling him the endings, it has been claimed.

Daily Record reports that the victim is now in intensive care with a knife injury to his heart.

He was flown from Russia’s Bellingshausen research station on King George Island to Chile following the alleged attack.
