Lees draws on Burroughs' search for an addiction cure to discover a ground-breaking treatment for shaking palsy, and learns how to use the deductive reasoning of Sherlock Holmes to diagnose patients. Lees follows Burroughs into the rainforest and under the influence of yage (ayahuasca) gains insights that encourage him to pursue new lines of pharmacological research and explore new forms of science.
