This book was actually better than I was expecting from other reviews, a charm is found at the scene of a murder and no one knows how it got there, then a second charm is found and both victims are related to the employees of a major company and so the security investigator starts to look for the link only to find himself as a target. Good for a quick read on a bus trip. Very old fashioned story telling so I am guessing it was written in the seventy's. No it's not a literary masterpiece but it was interesting enough for me to sit down and finish once I got off the bus.
