The interwoven TRUE stories of Marconi (the inventor of the wireless telegraph) and Crippen a very 'unlikely' murderer. Marconi is obsessed with his invention and stops at nothing to see it implemented. Crippen is a very ordinary man who probably (but maybe not) killed his wife, dressed his mistress as a boy and then fled with her across the ocean to America. Marconi's invention helped catch him. This book was good but a hard read. It took me forever to get through it. It was very educational and parts of it will really stick with me but it dragged in parts.
