This is one of those books I should have read years ago - I have seen it time and time again in the bookshop and other outlets on the Isles of Scilly over 23 years, where apparently over 100,000 copies have been sold since 1981. Written by a cousin of Robert Dorrien Smith, the lease holder of Tresco (and descendent of Augustus Smith, the "Emperor of Scilly" in the 19th century). It concerns an Irish Doctor, Nick Power, who in 1829 to escape a framed murder charge flees to America, and ends up shipwrecked on Scilly. He briefly becomes part of the local community, gets mixed up in smuggling and is forced to flee again, this time really getting to America, where he makes his fortune. He eventually returns to Scilly, where Smith is now installed as "Emperor", and reunites with his lost love. She however cheats on him with Smith, and he goes back to Ireland to face his accusers, discovering he is the bastard son of an Irish Lord, succeeding to the fortune, and vowing to use his experience to treat his tenants with kindness and compassion. The story is told through flashback to Power's childhood and the events in Dublin, and interspersed with the narrative of the story following his shipwreck.
If it wasn't (partially) set on Scilly I have am not sure I would have stuck with it, but I am glad I did. A little long (500 pages) and unbalanced, the last 10% of the book cover most of the plot action with everything settled in the last few pages. 19th century Scilly and the hardships people faced are however described very well. Smith is portrayed as a tyrant, but one who has the interests of the Islands at heart (although few of them appreciate it). The relationship between Nick Power and his best friend, Michael Fitzpatrick, goes through twists and turns, although eventually Fitzpatrick gets his just desserts for framing and cheating Power.
Hell Bay is on the west side of the island of Bryher, and can be very stormy in the winter, reputedly being a common place for shipwrecks to be washed up. I only ever see it in the calm Summer however when it tends to be very calm!
