Killers lurk beneath the waves of the western Pacific Ocean. The USS Encinitas, the first attack submarine crewed by both men and women, stalks the Crescent Moon, a renegade Iranian sub armed with nuclear-tipped missiles. But another predator hides aboard the American sub, a murderer who has already left a trail of dead women behind on shore. While the crew of the Encinitas plays a deadly game of hide-and-seek with the Crescent Moon, NCIS agent Linus Schag must discover the killer’s identity before his – or her – blood lust leads to the submarine’s total destruction.
How did you decide to create a trailer and what was your experience?
I think video trailer generate a lot of interest in readers. When I decided to make one for “The Killing Depths” I wanted to keep it simple — and cheap. I have a lot of experience using PowerPoint, as well as finding public domain photos and illustrations. I also had bought the rights to use the illustrations for my book cover. In my past career as a journalist, I had a lot of experience writing promotional copy for special projects, and I used that experience to write the copy for the trailer. Once I had the basic slide structure completed, I worked on the animation until I got the timing right. After that, I used PowerPoint’s built in ability to convert slide presentations into videos to complete the trailer.
What Inspired You to Write Your Book?
The protagonist, NCIS agent Linus Schag, was originally created for a short story that appeared in Alfred Hitchcock Mystery Magazine. I wanted to use Schag in a full-length novel, and hit on the idea of using a submarine as a sort of locked-room mystery sitting. It was a matter of coming up with an antagonist, a serial killer, and determining what the psychopathic drive for killing would be.
