"Detective novels are such a great genre of books, filled with with quirky private investigators, dark back alleys, sultry heiresses, and shocking villains.
I fell in love with Agatha Christie novels early on when I was young for reasons I don't entirely understand, but I've loved detective novels ever since. Most of the authors on this list have written multiple detective novels, but I tried to limit most of them to one or two entries, usually the first book in a series unless there's a particularly good or well-known book in the series. The only exception is Agatha Christia, who gets three because I love her!
Anyway, there's the list of the Best Detective Books of All Time! Happy detecting slash reading!" - The Bibliofile
