The novel “Agafonkin and Time” is the fourth book by Oleg Radzinsky. The hero of the novel, Alexey Agafonkin, is the Courier. But the courier is unusual: he delivers and picks up Objects from different time periods, moving between times, like others between cities. Agafonkin does not particularly think about the essence of the tasks received from the mysterious B, until he loses one of the Objects - a children's top. Both earthly and unearthly forces are involved in the search for the top, and the action quickly takes on the character of a race - who will get the top first? And why does everyone need it? It’s up to Agafonkin, and with him, the reader to find out.
