Continuing with Edward Haslam's work Dr Mary's Monkey.

...On my travels I had developed an interest in writing and started working on a book about my hitchhiking experiences. As the summer wore on , the publicity about the trial of the Manson murders in California took root, and the image of hitchhiking changed. Charles Manson and his companions had hitchhiked their way to one of the most grotesque multiple murders in American history. Everyone became aware of the real and present danger that lurked on the shoulders of our highways. Jack Kerouac's romantic vision of hitchhiking from 'On The Road' was replaced by Jim Morrison's stark warning: "There's a Killer on the Road'. My "hitchhiking for the fun of it" perspective suffocated, and my book project died. I started looking for something else to write about.

Mary Sherman's murder still intrigued me, and I thought it might have good potential for a screenplay. So I decided to track down the real facts. My first call was to the public library to see if there were any newspaper articles. I was informed that the indexing system stopped in 1963. If I wanted a newspaper, I needed the exact date. But I did not know the date, so I decided to try to get a copy of the police report. Based on what I knew about Sherman's murder and her connection to Ferrie, I figured this might be difficult. So instead of calling the police department myself, I decided to call someone "in the inside" who might be able to help me get a copy of the report quietly. I called Big Mike.
