One of my favorite authors is a relatively lesser known guy named James Swain. He writes a series of Detective mysteries. He actually writes a couple but I really like his "Tony Valentine" series. Tony is an ex-cop, private investigator in Atlantic City who specializes in "cheaters" who rip off casinos and other navarious, dastardly deeds.
Mr. Swain's obvious expertise in the subject of gambling, and the crimes and characters that go with it, makes this series entertaining and believable and exciting. His hero characters are well defined and human; with flaws to go with their heroics. His bad guys are really bad and his plots are not so technical as to be confusing but rather have just enough insight into the methods used by cheaters to be interesting.
I like the glitz and glamour of the casino locales mixed with the seedy underbelly of the criminal goings on.
I just wish there were more of them. I really enjoy Tony's adventures. I wish Mr. Swain a lot of luck in the future, and I am sure he is happy to be on my humble Favorites list.
