Clark's biography reveals the private life of J.B.S. Haldane - trail-blazing geneticist & physiologist, popularizer of science and dedicated Marxist. His relationships with colleagues & the political establishment were normally acrimonious - the reminiscences of friends & enemies, as well as his private papers, add the weight of personal insight to this examination of a great man.
