Protagonist (Ravic) is a skilled German surgeon who lost citizenship in Nazi times; he's illegally performing surgeries for two well-known (but not as talented) Paris surgeons. Can't get citizenship elsewhere. Action occurs between the wars. He meets various other stateless folks; it's an interesting/effective take on the way they lived. Occasional deportations. He lives in a hotel that caters to folks like this. Encounters an actress. I always enjoy Remarque's stuff, though didn't like this as much as All Quiet on the Western Front or Three Comrades.
