I can usually tell how much I like a book by how much time I spend thinking about it in between sittings. For this book, I read it so quickly, I didn't process my thoughts between sessions.
Fast paced, suspenseful, and fun to read, Eye of the Needle does everything it sets out to do. Characters and locations that feel insignificant upon introduction get rewarding (and at times rather grisly) payoffs.
As much time is spent developing the antagonist as any other characters, which is welcomed.
