A couple years back, I got hooked on &#34;true crime books&#34; set in the 1800s or early 1900s... call them &#34;historic true crime&#34; or maybe even &#34;literary true crime&#34; because of the quality of the writing.  (This isn&#39;t populist Ann Rule stuff!)  Here&#39;s one of my favorites from that sub-genre, about a notorious 1860 British murder, the enigmatic Scotland Yard detective assigned to solve it, the aftermath, and how the detective (Jack Whicher) inspired the writings of Charles Dickens and Wilkie Collins.
