She only has two win two more selection matches. Her biggest rival is Veerle Dingemans, who gets a very strict training schedule from her father Rob, who is an employee at the riding-school. The first day of the selection match Marie performs very badly. A bit later she drives with her moped against a clearly visible van and dies. A sedative is found in her blood. The investigations lead to Rob Dingemans. When he is arrested someone shoots him, but in the panic it's not clear who shot him.
