This was unusual, and not just for the author, who was probably striking out to do something different. The characters are very complex, even complicated, but the scenario is a bit melodramatic.
Some of my favorite things about Agatha Christie’s writing are also evident here, namely her way with amusing descriptions of people which are sharp but not mean.
So. Glad to have read her other work, still want to try Absent in the Spring…but this was not my favorite.
