Recommended for those collectors who want to get in on the ground floor. As the collecting of mystery fiction continues to grow, these titles, with their generally small print runs, have been the books that most rapidly appreciate in value. While we do not like to think of books exclusively as investments, it is impossible not to consider this element of a purchase. Previous selections have included Laurie King, Jeff Lindsay, Charlie Huston, and Chelsea Cain, as well as literary marvels like The Story of Edgar Sawtelle by Edgar Wroblewski, The Tiger's Wife by Tea Obreht, The Historian by Elizabeth Kostova, and Marisha Pessl's Special Topics in Calamity Physics.
