In South America the Saint meets two swindlers, Alice Nestor and her father. They show him a golden statue of a frog, claiming it is one of many such icons of the sacred frogs of the Incas and request that the Saint backs their expedition to find others. The Saint pretends to co-operate but plants some fake gold of his own to turn the tables on the swindlers, only to discover that they are also gun-runners for local revolutionaries.
