Alan Ainslie is an able and dedicated man high in the government. Daniel Ainslie, his son, is a member of an explosive movement impelled by the naive rebelliousness of the New Left. Hugh MacLennan weaves a complex and story of two generations in conflict. Originally published in 1967, Return of the Sphinx is something of a sequel to the more optimistic Two Solitudes and reflects MacLennan's disenchantment with the world in general and the apparently intractable French-English debate in Canada.
