Rick Geary's second volume of A Treasury of XXth Century Murder.
Famous Players - The Mysterious Death of William Desmond Taylor
"Geary takes the reader from the founding of Hollywood to its first major death, a scandal that would change the perception of the film Mecca of the world. On the morning of February 2, 1922, a servant finds one William Desmond Taylor dead on the floor of his home. The investigation into the murder would become a media circus that opened the public’s eyes to the secrets of the film industry."
