"Standard English Mystery with Dark Twists"
Interesting characters and plot twists that overcome the perfusion of standard mystery cliches.
The least interesting were the cliches themselves, some of which were taken right out of the pages of Conan Doyle (which of course were not cliches when he wrote them). These were so transparent as to be entirely predictable, and unlike their use by Conan Doyle really and little to do with the actual solution of the crime.
The most interesting aspect of the story was the juxtaposition of a standard turn of the Century English mystery with very modern literary themes.
Ellen Archer does a superb job of giving each candidate his or hers own identity. No mean feat given the number and nationalities of the characters.
