The novel “Marune: Alastor 933” by Jack Vance was published for the first time in 1975. It’s the second book in the Alastor trilogy and follows “Trullion: Alastor 2262”.

A man who arrived at the Carfaunge Spaceport appears to have no memory of his identity and there are no indications of the planet he has arrived from. He’s named Pardero after a hussade player but only so that he has a name. The psychologists he’s advised to consult try to awaken some memory in him but with no success.

Having established the impossibility of obtaining information about his origin from the man himself, an investigation is conducted based on his body language and appearance. The results point to Marune, a planet in the Alastor Cluster illuminated by four suns. After he arrives on the planet, he must get used to the customs of the Rhune people, of which he remembers nothing and consequently they seem completely alien to him.
