THE INQUIRY Will Caine, HQ £12.99

This topical thriller’s an explosive mix of politics, cover-ups, and the war on terror in the edgy post 9/11 years. Former MP Francis Morahan never wanted to get involved with politics again, but the senior judge finds his arm twisted to head up a secret inquiry into the success and failures of intelligence agencies fighting the growth of homegrown terrorists inspired by ISIS. His best weapon is young lawyer Sara Shah who once flirted with dangerous organisations herself, and knows the shady routes that lead to the planners of atrocities.
