Baba

Underneath the surface of charm, Baba is a combination of a Mitford sister and a Machiavellian old woman.

Calculating and intimidating she runs a tight operation using fear, subjugation and small acts of kindness to acquire utter loyalty from her 'family'; the 'family' she has deliberately chosen and brought together. She utterly relies and trusts Frank, only ever refusing his advice when it comes to the subject of Toby, her treasured grandson. In Luther, Baba has spotted the perfect opportunity to have an insider on the police force, she believes him to be Frank's successor as chief 'security advisor'. But Baba has underestimated Luther's resilience.
