Mysterious Top Tens.

There are three interesting lists posted on the Mysterious Matters blog (written by an anonymous mystery editor):

Top Ten Ground-Breaking Mysteries (including Charlotte Armstrong's A Dram of Poison and The Dream Walker, as well as Patricia Moyes's Who Is Simon Warwick?)

Top Ten Reasons to Read a Mystery (including "to escape a messy world with no plotline and no consistency of characters")

Top Ten Plot Devices That Make Me Want to Scream in Horror (including "narrative as psychotherapy for the author")
