Nautilus — Larry Jeram-Croft

1805, the year Napoleon plans to invade England and the year Jacaranda and her crew have to return to in order to rescue Smithy the scientist, whose experiments have sent him back to England of the past. They meet up with their friends Charles and Melissa as well as Sir Sydney Smith, a renowned naval officer and Robert Fulton the man who invented the world's first workable submarine, the Nautilus. However, nothing is simple and in order to return to their future they must sail Jacaranda to Cadiz where the combined French and Spanish fleets are sheltering. Here they must help Sir Sydney to entice the French out to sea where Nelson's fleet is waiting. Many of the French also want the confrontation and with the aid of the Nautilus a daring raid on Cadiz harbour is undertaken. Once again the story is based on real events and characters of the time.
