David Marshall's "The DD Group: An Online Investigation Into the Death of Marilyn Monroe" is a must-read for anyone interested in learning the truth about the premature demise of Hollywood's most enduring star. The book examines all aspects of Miss Monroe's death by carefully reconstructing her final hours and analyzing the facts in a logical, detailed, and organized manner. Medical and forensics evidence is carefully dissected, and the possible agendas and questionable credibility of several key associates of Miss Monroe's {as well as a number of contemporary biographers} is presented for consideration. The book contains numerous startling new facts never revealed in any other Monroe biography, information which is compelling, ground-breaking and startling in the extreme. The intense research conducted by the participants of the group is impressive and unprecedented, and Mr. Marshall did an admirable job condensing what must have been an intimidatingly vast amount of information into a concise, well-written and thoroughly gripping investigative report. I highly recommend this book to anyone searching for the truth about what happened to Marilyn Monroe on the night she died. Fact and fantasy will become very easy to discern, and readers will arrive at a possible conclusion which is credible, realistic, and devoid of sensationalism. This book is a tremendous accomplishment, and you will never look at the death of Marilyn Monroe the same way again.
