KENNETH ROBESON – The Other World. Doc Savage #83. Bantam F3877, paperback, October 1968. Previously published in the January 1940 issue of Doc Savage Magaine.

   The struggle between two fur dealers over strange and beautiful furs leads Doc Savage and his crew to an underground world, the entrance to which is hidden somewhere in the Arctic wilderness. This world still lives in prehistoric times, with the usual assortment of dinosaurs and other menacing creatures.

   The villains are vicious – to stop a letter from getting to Doc Savage, they simply smash the mailbox open with a sledgehammer – and in spite of being short on science, scenes in the other world (especially the one illustrated on the [paperback] cover) are exciting, But the idea is not new, rather third – or fourth-rate by this time
