Dennis Koller Releases 'The Oath'

A lifetime ago, two young naval aviators took an oath to "defend the Constitution of the United States against all enemies, foreign and domestic." Both were shot down over North Vietnam and endured years of brutal torture in the same prisoner-of-war camp.

Now, one is a San Francisco homicide inspector, with his allegiance firmly anchored in the law. The other remains steadfastly allegiant to the oath and is systematically eliminating Americans who had visited North Vietnam to aid the enemy's cause - Americans he views as domestic enemies. The lives of these two former POWs are about to intersect again, and the consequences will be explosive.

In The Oath, author Dennis Koller creates a gripping, stay-up-all-night mystery-thriller that expertly intertwines the compelling stories of two former POWs with a modern-day murder investigation.

The book opens with the cold-blooded murder of a famous San Francisco newspaper columnist. Homicide Inspector Tom McGuire is called to investigate a scene that's unlike any he's seen before. The victim was shot in the head - execution style - and her arms were bound behind her, the rope knotted tightly from shoulder to wrist.

Awash in an eerie chill of recognition, McGuire is transported back in time to the infamous Hanoi Hilton where as a POW he endured rope torture many times, his arms tied in exactly the same fashion.

The medical examiner - already on the scene - explains that the victim was shot and killed before she was tied up. The killer, it seems, is leaving a calling card that only a select and unfortunate few would recognize.

As the killer's identity slowly comes into focus, McGuire is forced to face his own demons and reluctantly pursue a brother-in-arms. Will McGuire remain allegiant to the law or to the oath he shares with the killer?

Born and raised in San Francisco, author Dennis Koller was the Executive Director of the SS Jeremiah O'Brien, a World War II Liberty ship berthed at Fisherman's Wharf in San Francisco.

In 2013, Koller figuratively "jumped ship" to write his first mystery-thriller, Kissed By The Snow, about a secret FBI drug taskforce that devises a plan to finally win America's war on drugs. The book placed fourth in the Ink & Insights national writing contest.

He is also the author of The Custer Conspiracy, published in October 2016, which was named a 2017 Distinguished Favorite in the thriller category by Independent Press Award.
