It was interesting to read them end to end. Though the dates of their first publication were ten years apart, there were several noticeable similarities. Both are set in remote locations on or near the Dorset coast (The Skull Beneath the Skin takes place on an invented island), both feature rather bizarre and sinister households presided over by decidedly strange aging men with peculiar menservants, and in both novels a small Victorian marble carving is crucial to the events surrounding the murder.
Of the two, I preferred The Skull Beneath the Skin. I think this owed a lot to the presence of Cordelia, an attractively unusual though highly professional private detective. In this novel she is asked to go to a reconstructed Victorian castle where a semi-amateur production of Webster's Jacobean drama The Duchess of Malfi is to be played for just one performance, with the celebrated actress and aging beauty Clarissa Lyle in the leading part. Lyle has been receiving death threats, and her husband has hired Cordelia to protect her. Though she does her best, needless to say Clarissa is murdered. Most people on the island seem to have good reason to do away with her -- of course it's a classic locked room, or in this case cut-off island mystery -- but the perpetrator is, again needless to say, the person who seems the least likely in every possible way. And yes, Cordelia does work it out, though she is distressed by what she uncovers.
It sounds as if I'm being a bit sniffy about these two novels, but in fact they were both highly readable if somewhat macabre. I commented to a friend when I was reading the first one that it was nice to read some grown-up writing for a change. Good well written prose, plenty of literary references, intelligent and thoughtful, and clearly aimed at well-read adults. Call me old-fashioned if you like, and you'd probably be right. But James certainly knew how to craft a complex plot and to create excellent, if rather odd and rarely likeable, characters. Maybe there are one or two more of her novels that have slipped through my radar -- I rather hope so. She was a hugely talented writer and an unforgettable woman.
