Emily Muller is kidnapped from a parking lot after shopping in the nearby mall. Her husband, Duncan, is just yards away at the time, and despite a chase, he is unable to save his wife when she is driven away at high speed in her own car. At first, the team suspect that it may have been a carjacking gone wrong, but when a witness suggests that Emily may have recognised the assailant, they think again. The team uncover some secrets in the Muller household which lead them to believe that Duncan may be involved, especially when they discover that his business is in very serious financial trouble. However, some clever detective work from Martin changes things and the investigation is quickly diverted.
