David Warner 

Every Cluedo mystery needs a man of the cloth. Warner is the red rag to his own bull. So much of the blame for this series should be laid at his feet. His promotion to the vice-captaincy was always a risk, unless of course you take a rather literal interpretation of the word 'vice.' Cricket Australia (CA) have no one to blame but themselves. He is clearly ill-suited to any role that involves mature self-reflection and wisdom.
