'Felix de la Rosa had no need for a map, nor a compass, to navigate his way through the Amazon. For many years he had, literally, followed his nose and this time was no exception. You see, Felix’s nose was rather extraordinary. To the naked eye it did not appear to be a particularly interesting or spectacular proboscis - ugly, disproportional and slightly askew - certainly not the sort of snout that an olfactory chemist dreams of.'
