Agatha Christie's "voice" is ironic and provides an interesting view of the (sometimes exceedingly tedious) upper classes with which she was so familiar. Her usual plucky female lead character ("Bundle") is present, as are several suitable young "asses," (her word for them, and I agree), but Superintendent Battle provides a nice balance of adult common sense. Lord Caterham is a riot and a fun character to follow. Class and race prejudices are now politically incorrect, but Dame Christie had no qualms about expressing her views. If the final exposition is a bit too long, that was the style of her mysteries and a bit of a let down at the end.
