In Nuts and Bolts, award-winning engineer and broadcaster Roma Agrawal deconstructs our most complex feats of engineering into seven fundamental inventions: the nail, spring, wheel, lens, magnet, string and pump. Each of these objects is itself a wonder of design, the result of many iterations and refinements. Together, they have enabled humanity to see the invisible, build the spectacular, communicate across vast distances, and even escape our planet.

Paris. An old mystery. As midnight strikes, a man desperately seeking sanctuary flees into a church. The next day, his sudden disappearance will make him famous throughout France. A new science. Forensic expert Enzo Macleod takes a wager to solve the seven most notorious French murders, armed with modern technology and a total disregard for the justice system. A fresh trail. Deep in the catacombs below the city, he unearths dark clues deliberately set - and as he draws closer to the killer, discovers that he is to be the next victim.
