My days are usually pretty humdrum. Certainly, since my wife ran off with a professional golfer and took our daughter with her. Amanda and I fell in love in college, and I brought her back to my hometown of Brunswick, Maine. We got married. Had a little girl. But something was missing.

Amanda was not happy with my chosen profession, private detective. She claimed that a person couldn’t make a living in small town Maine in such an occupation. It seems that she was right, but luckily, my crazy Aunt Zelda died and left me an inheritance, one that allowed me to open a mystery bookstore to complement my income. I named it after my dog. The Coffee Dog.

My friends would say that I am a mass of contradictions. It is true that I am a private detective and a bookstore owner, meaning I occasionally carry a gun but like to read. I support the environment and I eat red mean and played football. I sometimes forget to put the top up on my convertible when there is frost in the air. The result is my hair freezes.

The most important thing in the world to me is my daughter. I am not above playing Barbies or dressing up as a princess if that is what she wants. Being a good father supersedes anything else in my life. I am not sure if I still love my wife but know that I miss my daughter more than anything.

My days consist of selling books where the protagonists are engaged in high stakes play—saving the world, running down murderers, and uncovering corruption. The reality of my personal private detective firm is taking pictures of cheating spouses and revealing false workman compensation claims.

That is, until recently, when the Widow Dumphy hired me to track down who had killed her husband, the head of security at the local nuclear power plant. It seems that the Chief of Police had some involvement, radical environmental groups seem to be in play, and even the governor of the state might have a stake in this recent case I’ve been hired to investigate.

It is important to mention that I have a supporting cast of friends that back my every play. The huge bear of a cop, Bart, the hippie lawyer, Jimmy 4 by Four, the immigrants Richam and Jewell, the college student Peppermint Patti, and my sole employee and desire, Chabal.

My daughter returned but was almost immediately threatened by a strange looking man who calls himself Shakespeare. The man punched Jewell, pistol whipped me, and injured the Coffee Dog. Things have grown far more serious in my life.

The further into the case I dig, the worse things get. My friends and family have become endangered. If I don’t make it through to the end, I’d like to confess.

It is my fault that the girl is dead.

With the help of Bart, the bear of a cop; Jimmy 4 by Four, the hippie lawyer; the immigrants Jewell and Richam; and his true desire and employee, Chabal—Langdon sets out to do just that. And then he is framed for not one, but two murders, and events become very complicated.
