Recent experiences of reading Darkness at Pemberley by T.H. White and What a Body! by Alan Green — oh my days, I’ve only just noticed that they’re both named after colours… — have made me wonder on the above question. See, both are listed here, on a compendium of the best ever locked room mysteries voted on by an international collection of people who know about this stuff, and both are listed here, on a rundown of the favourite locked room mysteries by resident blogosphere expert TomCat…yet personally, in the face of public opinion from such well-informed and respected sources, I’m reluctant to consider either of them as locked room mysteries. Even taking my famously contrary nature out of the equation…what the hell?
