One of the few times that I could have tolerated a description of apes being both violent and carnivorous is in this Kolchak story. In so many science fiction items apes are killers and aggressive. Actually they are vegetarians and shy though they fill to defend themselves.
But Darren McGavin is dealing with some cells that grew overnight into a killer ape. They were found at an Arctic oil drilling site and they came to grow when the cooling system at the lab in Chicago failed.
Once again McGavin is feuding with all, be it boss Simon Oakland or the police in the person of John Marley. He also is unusually ingenious and sneaky in his pursuit of the story.
It's the Kolchak I like to see.
