["Dragon's Island"] falls into the suspense-melodrama category, and very satisfactorily. The science element involves "genetic engineering," the deliberate manipulation of genes to produce new biological results—even a new race of mankind. The melodrama involves private detectives, amnesia, switches of identity, an ambiguous heroine and other standard devices so nicely calculated and integrated that they seem fresh and exciting. The story happens in no vast intergalactic future, but right here and very nearly right now; and the result is something like a Hitchcock film in quasi-scientific terms—guarantee to jerk you to the edge of your chair with each new plot-twist.
