Sleeping Murder by Agatha Christie
My rating: 3 of 5 stars
This book was written waaaay before it was published in 1976. It sat in a deposit box waiting for the light of day. So there may be some inconsistancies with the rest of the series...but Miss Marple is not a series that you have to read in-order, in order to enjoy it.
That being said, I can see why this book was slotted for the end. The crime is two decades old, a "sleeping murder" or a "murder in retrospect" that is triggered by the main character's (Gwenda) childhood memories. Today we'd call a case like this a 'cold case'. By utilizing a murder-in-retrospect as the central mystery, Christie creates a reflective element that enhances the book itself, and also her series in general.
Let me clarify that last statement a little bit. Miss Marple is a character who has solved, and survived, many different cases. At the opening of this particular case, she is hesitant to wake it up. "Let sleeping murder lie." But there's no way the two main characters, Giles and Gwenda, will let it rest. It doesn't matter how old the case, it needs solving. Miss Marple, of course, joins them in the investigation in spite of her reservations.
By focusing on this type of case, Christie seems to emphasize that no case is unimportant, no case it too old to ignore, and therefore, all of Miss Marple's cases are important, and no book or puzzle is too old to ignore. As a final book, Sleeping Murder gives the Marple stories a certain gravitas. It's worth reading just for that.
