HE LIMBO LINE

A case and a chase for Richard Manston, who had retired from undercover work but is persuaded to tail one Irina Tovskaya, a Russian ballerina who had found political asylum in England, up to the ""Limbo Line"" when she is to be returned behind the Iron Curtain. In and out of the hands of the alien organization, AGRIP, they head through the south of France, to a chateau- and a rock chamber, a countess and a priest... All the class and speed of a foreign sportscar as it streaks across the continent.
