The crime
The murder of Marilyn Sheppard (aka “the Fugitive case”), the poisoning of Ada Appelgate, and a handful of others.

The story
I had read bits and pieces of Dorothy Kilgallen’s posthumously published Murder One before, of course — it’s a seminal text, for true-crime reviewers and for book dealers. Among the latter, it seems like the same 12-15 copies keep rising and setting over eBay’s fruited plain; I’d flipped through various copies, primarily to assess them as to condition but always skimming a few pages at the same time, waiting for a copy to present itself that I considered sufficiently busted to buy for/from myself at cost.
