Darkest Tunnel

The Philadelphia Police Department commissions Spots to investigate the rape and murder of a prominent businessman’s daughter. The chase becomes a twisted cat-and-mouse game that unleashes Spots’ unforgiving tenacity. A serial killer’s rape and execution of women in modern-day Philadelphia ends in poetic justice for the residents of the rich and powerful world they create.

Prior Book Reviews
Criss Cross: “Fast, easy who-dun-it. You will be surprised . . . This is one of those thrillers that makes you want to read the next one. I was pleasantly surprised at the depth of character development.”

Finding Aaron Laws: “A real page turner! A must read! I was completely immersed from the first page—one of Mr. DeMark’s best. You must read Criss Cross, his first book. I will be waiting for the next.”

The Ethos Syndrome: “Third book in this series. I’ve read all three. This has to be the most intriguing of them all. Suspense builds in this unusual story line almost from the beginning.”
