An enthralling story about desire, new love and the mysteries of science from the Pulitzer Prize-winning author of The OverstoryStuart Ressler, a brilliant biologist, sets out in 1957 to crack the genetic code. His efforts are sidetracked by other, more intractable codes – social, moral, musical, spiritual – and he falls in love with a member of his research team.Years later, another young man and woman team up to investigate a different mystery – why did the eminently promising Ressler suddenly disappear from the world of science?Strand by strand, these two love stories twist about each other in a double helix of desire.‘A love story of charm and substance, brimming over with ideas, yet anchored in emotional truth’ Sunday Telegraph
