Once upon a time, an irreverend 24-year-old American biology postdoc and a mildly eccentric British physicist worked together at the Cavendish laboratory at Cambridge. They tinkered with models to find a structure that fitted the X-ray diffraction patterns that others had measured of DNA, and they discovered the double helix. They became very famous and lived happily ever after. This is the story James Watson has told the world in his famous memoir "
Double Helix", first published in 1968 and translated into numerous languages. Although one may argue about the way he treated some of the people involved, including the late Rosalind Franklin, it has deservedly become a classic of science writing.
Girls Genes and Gamow is a sequel, promising us some details of the "happily ever after", aiming to back up Watson's claim that, thanks to the double helix, he has led an extremely interesting life in science. The only trouble is: the data he presents here don't support this claim. What he did next was to spend a year at Caltech, making theories about how DNA sequences lead to proteins, none of which worked out (while Crick proposed the adaptor hypothesis, which did: adaptors are now known as tRNA). Genes? What genes? Not much more luck at the girls front. Given that he characterizes the women in his life mainly by their hair colour, and expresses surprise that Christa Mayr, daughter of the acclaimed biologist Ernst Mayr, could keep up her end in serious conversation, readers may feel like congratulating those that got away.
And finally "Geo" Gamow: yes, he must have been an interesting character, but he doesn't really come alive on these pages. The same holds for Richard Feynman whom Watson met regularly. (Now that's at least one person who had a more interesting life in science.) Still, writers can get away with flat characterizations of their cast as long as they have a plot. What makes this book fail where the double helix succeeded is the nearly total absence of a structured plot.
