A boy is playing with his remote control red Corvette in an empty warehouse when he overhears voices. He hides himself and witnesses two men killing another man and throwing his body in an industrial oven. However the murderers find the boy and he disappears. Two months later, the remains are found and the CBI agents investigate the warehouse and Patrick Jane finds the little red Corvette hidden in a corner and believes a boys has witnessed the murder. They identify the victim as the geologist Horatio Jones, who had worked in the Amazonas forest and would testify against Tommy Volker two months ago and went missing. The DNA evidence shows that the killers were Charles Milk, who was recently murdered, and Don Clyde. Meanwhile the CBI team follows other clues to catch Volker but Lisbon and her team do not know that there is a breach in CBI security and the PR Brenda Shettrick is leaking information to Volker.
"Little Red Corvette" is a great episode of "The Mentalist", with Lisbon obsessed to catch the omnipresent Tommy Volker. This episode also discloses the identity of the CBI employee responsible for the leak of information. My vote is eight.
Title (Brazil): "Little Red Corvette"
