Terrifying and exciting, I could not let go.

Bourgouin was the first to address the relationship between the Black Dahlia murderer and a serial killer in Cleveland who has committed more than a dozen crimes from 1934. I had forgotten but it recalled in his book. He did it in a preface to the memoirs of Eliot Ness, The Untouchables. I just watched my copy of Black River edition, preface Bourgouin was in 1993, long before John Gilmore and his book "Severed" or any other American books. And Gilmore has never made the connection between these two criminal cases, that of Dahlia and Cleveland.

In the chapter How I tracked the Black Dahlia killer, Bourgouin explains, step by step, how it worked, accumulating thousands of tables on cold cases, and working as a real profiler, to find similarities with the ritual murder of Elizabeth Short. It's fascinating - and impressive. In the end, his theory is validated by the FBI profilers. Bourgouin is absolutely honest with the reader, he tells us his doubts and never guarantees 100% his hypothesis, unlike many others who have written about the Black Dahlia.

Photos (there are over a hundred) are sometimes very violent but they are necessary to make us understand the horror of this crime.

Finally, a book that reads like a thriller. I could not let go. And then we can truly say that truth is stranger than fiction.
