Most underrated mystery novel

Many of you have asked for posts on the most underrated books.  Today will start a short flirtation with this topic ("underrated week," which of course starts on Friday) and we’ll break books down by category.

For mystery, I’ll nominate the works of Henning Mankel, although arguably he is not underrated any more by critics.  Verissimo’s Borges and the Eternal Orangutans is my other pick.  Or how about Charles Palliser’s The Quincunx?
