Crime Thriller

Unit 33

Nine cases. High-stakes crimes. One elite intelligence unit.

By Dennis Dalton

From murders and kidnappings in South America to audacious bank robberies in California to extracting sensitive files from the Middle East, Unit 33, a privately owned secret intelligence unit in the heart of downtown San Francisco, works covertly to assist various global banking corporations in their fight to maintain security for their clients and assets.

Dan Holmes, security expert at 2nd National Bank, runs the private covert securities operation unit adjacent to his bank. Unit 33, often working with connections cultivated in government intelligence and foreign spy agencies such as Mossad, works to expose financial crimes and malfeasance.

In this collection of nine stories, Unit 33 and its agents interrogate criminals, skirt the edges of the law, and find their personal lives invaded by the violence of their professional lives.

Step Inside the World of Step Inside Unit 33

Nine stories. Endless deception. It all starts here.

The Night Abbey and Ron Saw Too Much

San Francisco is like any other large city when it comes to never sleeping—there is always someone, somewhere, awake, who witnesses whatever goes down. With everyone carrying their own phone, whatever is witnessed has the potential to go viral almost immediately. It’s as though the whole city is continuously watching…just waiting for something, anything. Take, for example, a couple of weeks ago, just past midnight near the front of the Hyatt Hotel at Embarcadero Center.

This is a time when the only people awake are the guards in the lobbies of high-rises. The cleaning staff is busily cleaning the offices dozens of stories above the street or taking their break. Out on the street, there is always that one person or a couple of out-of-town business people staggering back to the Hyatt after a night of too much to drink and too little to eat. Then again, there might be that romantic couple rushing to catch one of the last Bay Area Rapid Transit trains.

Such was the case for Abbey and Ron, or at least that’s how Ron saw it.
