The Schooner Columbus is a fascinating story by the talented Ukrainian writer Mykola Trublaine.

The boy Hrytsko had just reached out his hand for a bright flower when someone called out to him. Behind him stood a tall man in a white cap and a cloak on his arm. He had two cameras on his shoulder. He asked where fisheries inspector Kovalchuk lived. A man like a man. But still, he looked like a stranger to the boy. And he was not mistaken.

The photographer Anch, who was staying with Kovalchuk, was a spy for a foreign country. With a terrible intention, he made his way to the Soviet Union - to destroy Professor Ananiev, to steal his project to extract helium from thorianite. But events unfolded in a completely different way from what the experienced spy had expected.
