The novel “Creatures of the Abyss” by Murray Leinster was published for the first time in 1961.

Terry Holt has been running a shop in Manila for a long time and his electronics skills allowed him to do good business until his partner caused a lot of trouble for the business. He’s about to leave the Philippines when he receives a very important offer that leads him to join a scientific expedition led by Dr. Morton.

His ability to create high-level radar systems takes Terry Holt into the ocean for a research on the mystery related to strange marine phenomena. What fishermen call las orejas de ello are considered only a legend, but certain events convinced someone that it’s the type of legend that has a basis in fact.
