Puerto Vallarta, Jalisco, Mexico - James R. Callan, a part-time resident of Puerto Vallarta and long-time member of the PV Writer's Group, has just released his twelfth book, Political Dirty Trick. Packed with suspense, politics and murder, this riveting thriller will have readers on the edge of their seats.

After a successful career in mathematics and computer science, receiving grants from the National Science Foundation and NASA, and being listed in Who's Who in Computer Science and Two Thousand Notable Americans, Mr. Callan turned to his first love - writing. He has had four non-fiction books published. He now concentrates on his favorite genre, mystery/suspense, and Political Dirty Trick is his eighth published work of fiction.

In addition to writing, Callan also speaks at writing conferences and teaches writing workshops in Texas and Mexico. While speaking at the Silver Leos Writers' Conference, held last week at Texas A&M University-Commerce, Callan gave attendees an overview:

"My newest novel is not funny. It's Political Dirty Trick, the third in the Crystal Moore suspense series. Crystal's good friend Ron Drake is running for the office of governor of Texas. Some believe a political dirty trick might derail Drake's fast moving campaign. But something goes terribly wrong with the trick and a man is killed. And things go downhill from there.

Crystal is determined to find out who is providing fake news to the media. As she finds clues, she becomes a target. Soon, it's not a question of whether Drake will win or lose, but whether Crystal will be alive to see the outcome."

"Powerful in its characterization, plot, and narrative interactions, "Political Dirty Trick" is the item of choice for thriller readers who like their stories steeped in realistic scenarios and possibilities." - The Midwest Book Review Senior Reviewer Diane Donovan

Political Dirty Trick is available in paperback and Kindle editions at Amazon.com.

James and his wife, Earlene, split their time between homes in northeast Texas and Puerto Vallarta, Mexico. To learn more about the author and his works, visit his website, blog, or author's page on Amazon.com.
