I looked forward to reading this one, as I have a particular soft spot for Holt's Cornish novels, but something wasn't entirely satisfying about it. I think part of the trouble was that it takes Ellen, Our Heroine, an absolute age to get to the Cornish island. We spend nearly 100 pages in London with her repellent cousin Agatha. When she does finally get to Far Island, the book exudes huge promise. We have the very Gothic Kellaway Castle (complete with dungeons of course), and the two smaller islands nearby, one of which is inhabited only by a solitary artist. There are all the classic Holt ingredients: dark family secrets, a mad half-sister, a Byronic/Heathcliff-style love interest, an underground tunnel, secret passages, and a few attempts on Our Heroine's life. But it all feels too rushed. An awful lot of plot is crammed into the remaining 150 pages, and I wished she had taken her time more with it, fleshed it out more. There was too much of a feel of A Deadline Looming. Some of the characters aren't developed at all. Gwennol for instance doesn't end up playing as important a part as I thought she was going to. Never mind though, it's all still well worth a read.
