Private investigator Max McShane encountered a familiar sight Monday, entering his Bourbon Street office to find his file cabinets overturned, his spare necktie slung across a blade of a still-rotating ceiling fan, and his black, rotary-dial phone buzzing off the hook. 'I just cleaned up this place from the last ransacking,' McShane said. 'Someone obviously wants me off the King murder case. Unless last Friday's ransacking was to scare me off the King case. Then this is probably about the Adams diamond theft.'
