Jack Higgins may not be running out of his fascination with modern weapons, fine dining, glamorous women or the IRA but he appears to be slipping on plot and character development. Sean Dillon makes Doc Savage and Dirk Pitt look like pikers. And this curious extension of gentlemanly methods for attempting to kill one another -- sending a crazed assassin and then both sides meeting later at the Savoy to exchange notes -- strains credulity.Higgins has done some first-rate work. Had this been published twenty-five years ago, this might have made a difference. It wasn't and it doesn't.
Negative

Does a great job highly visible. Works well with the different fencers that I use in the different pastures. Last a long time. Can't beat it for the price.
Positive

John Keel's "The Mothman Prophecies" follows a usual form for ufology books: He presents a large collection of anecdotes, personal observations and experiences, mixes it with some debunking to woo the scientific mind, and throws in some ancient gods and goddesses, references to fairies, and a variety of religious "sightings". This is par for the course in this genre, and puts this reviewer in mind of Charlie Brown's standard beginning for tales, "It was a dark and stormy night."Despite its rather disorganized and somewhat repetitive presentation (again, fairly standard for this genre), Keel relates his narrative earnestly, and he will engage your interest. Men in Black? Saucer shaped vehicles with diamond-shaped windows? "Thyroid-like eyes"? If this gets your attention, you'll enjoy "The Mothman Prophecies."The recent movie is based only loosely on Keel's research, by the way, and will fail to satisfy informed ufology readers.
