The title "Whorl" comes from the name of a spiral or circular pattern, often associated with human fingerprints. The study of human fingerprints, also known as dactyloscopy, classifies fingerprints into three distinct categories: loop, whorl and arch. The unique nature of human fingerprints is at question in the novel when an FBI lab technician discovers that the fingerprints of an FBI special agent applicant matches two other individuals in the system.
This discovery threatens to throw legal systems across the world into complete chaos, since more crimes are solved using fingerprint evidence than any other kind of evidence. To prevent the wholesale dissolution of world legal systems, government forces attempt to erase all evidence of this discovery, threatening the lives of both the FBI lab tech and the special agent applicant, Dave Anderson. The setting for this story is Detroit, MI, a city with which Tarr is intimately familiar.
A former police officer and private investigator, Tarr currently writes for a number of outdoor publications. Tarr is a contributing editor for Handguns, RifleShooter Magazine and Firearms News. He is also the co-host of the Sportsman Channel TV show "Handguns and Defensive Weapons" and also appears on the TV show "Guns & Ammo."
Tarr is also the author of several other novels, including "Failure Drill," and co-authored Dillard Johnson's Iraq War memoir, "Carnivore." He currently lives in Michigan with his fiancée and two sons.
"Whorl" is available on Amazon and retails at a suggested price of $14.70.
