Gray Barker’s work is second only to John Keel’s on the subject of the Mothman, since he was investigating it directly at the time of the events. However, The Silver Bridge comes off more prosaic, almost as a pulpy novel based on the occurrences rather than any substantial treatise or history of the events surrounding Point Pleasant, West Virginia.
Mind you, some of the events he chronicled have different points of view than Keel’s work, and some of the events I hadn’t heard of either. I accredit this to the veils of secrecy both writers (and most paranormal authors) tend to work under to keep their accounts either fresh, unreported, or unbiased.
The style of prose and writing is fine, but there’s way too many changes in point-of-view to follow some of the story easily. Many small but strange events are mentioned and then never referred to again, leaving the reader to decide if and where they fit into the grand scheme of things. Very little of the story is actually about the destruction of the Silver Bridge itself, and the final bit involving it it confusing beyond belief, as it chronicles an event I had never heard of in the lore before this book.
Still, I’d have to recommend any cryptozoid fan read this one as a matter of course, so you can really make your own mind up about the Mothman.
