With the UK terror threat level raised to severe, Julia Montague holds secret meetings with the director general of the security service - freezing out her own minister for counter-terrorism and the police, led by Commander Anne Sampson. David Budd is on high alert as the home secretary's hardline stance on national security propels her further into the public eye, and the specialist protection officer comes under pressure from senior police officers to spy on her.
