This book is a very good first hand account with the dog man or American Werewolf. Mr. Groves is a retired law enforcement officer, so his words have a lot of credibility. Especially since his story was kept quite for many years because of his employment. Now that he's retired, he can tell his story. Overall, A great story by an eyewitness.
This is a frightening and terrifying account of the author's experience encountering Dogmen. He and his friend were fortunate to survive, though his friend was never the same again. I first heard his story on a podcast show and had to get his book. The author is a former Sheriff's deputy. He also notes the LBL massacre in this book as well, though he wrote another book as well. Both are excellent and worth your time.
Crazy story if true and worth the read if this subject interests you. Plus it's a quick/fun read that can be knocked out in one afternoon. Only negative is it has decent amount of typos and grammatical mistakes, but it's not enough to hamper the experience in my opinion.
This is a book by Martin groves, a retired law enforcement officer with countless awards and great credibility detailing a encounter he had with multiple creatures in LBL Martin changed my view on these creatures and I believe him whole heartly.
