Death on The Lizard

Lizard Village, 1903. 

Cornwall is rich with natural wonders, but these natural beauties conceal dangerous secrets, as amateur detectives Lord and Lady Sheridan discover. Wireless telegraph companies around the world are scrambling to develop new communications technology. 

But an Italian named Guglielmo Marconi beats them to it. His feat has bruised some egos, but no one expects sabotage, much less murder. After two apparently accidental deaths at the Marconi wireless transmission station, Lord Sheridan and his wife Kate investigate.
