The Imprudent Professor

Emma Bartlett asks the Saint to guard her father, a scientist who has recently invented a petrol substitute. She is concerned that he may be kidnapped or forced to defect because of his product. After a confrontation with a man who claims to be a secret service agent responsible for the professor's well-being, the Saint runs into the seductive Samantha, who works for the organization Genius Inc. which sells very clever people to the highest bidders. Meanwhile the professor disappears, lured by a fake telephone call to meet up with the Saint, who must rescue him before his kidnappers can take him out of the country.
