Anne Barton writing as Carolyn Dale
When a bloodstained knife is found in the Dragon Fountain on the grounds of Drayford Agricultural College, located on the Alberta prairies, it leads to the discovery of a professor who has been murdered in his home. Gail and Anton Schild are suspected since they had dinner with the professor on the night of his murder. They inadvertently remove a piece of evidence from the crime scene, and unwilling to admit having done so, they try to investigate the murder on their own. Their investigations take them to the dinosaur museum and to the hoodoos. But someone does not want them snooping around.
