Friday Barnes 12: Collision Course: The Bestselling Detective Series

Friday Barnes is Europe's most wanted in this latest installment of the bestselling detective series.

Friday's Mum, the Nobel Prize winning physicist, has been accused of espionage. The police think she's been selling secrets about the CERN Hadron Super Collider. Friday knows her mother isn't capable of such a thing - this is a woman who can't even operate a dishwasher.

She's got to smuggle herself into Switzerland to clear her Mum's name. Fortunately, Melanie is a master of disguise. After an extremely extreme make-over, Friday arrives at CERN and finds axolotls in the water coolers, graffiti in the great hall and most baffling of all - her sister has fallen in love with an engineer! Can Friday solve these mysteries? Can she keep her family out of prison? And can she recognise Ian if he shaves his head?
