Query: The truth about America's most shocking crime

The Black Dahlia case is one of the most famous unsolved murders in American history, but unfortunately one of the most misunderstood. Many writers have written about it, few with any degree of accuracy. Luckily, John Gilmore has cut through the crap and written "Severed", the only authentic account of the Black Dahlia murder. Exhaustively researched and compellingly written, Gilmore's account unearths the truth about the life and death of Elizabeth Short. In the process, he explodes some of the myths concerning the Dahlia case: Short was not a hooker, a lesbian, or a porn actress. Gilmore is the only writer to portray Short thruthfully, as she was in real life, through extensive interviews with those who knew her. And possibly, Gilmore is the only writer to discover the true identity of the man who dumped her corpse in a vacant Hollywood lot, neatly sliced in two. "Severed" is the last word on the Black Dahlia murder
