The De La Cruz Case Files

On April 23, 2018, Cleveland Homicide Detective Jesus De La Cruz’s life is going to get complicated. From Down&Out Books.

An unknown killer is waging a war on drugs. The murders are horrendous but with a silver lining—now stop signs are the only objects lingering on corners in the city’s toughest neighborhoods. Half the city calls for the police to end the killer’s reign. The other half cheers the killer on, denouncing the tactics but celebrating the progress police haven’t been able to achieve.

The gritty details of Cleveland’s drug underworld are nothing new to Homicide Detective Jesus De La Cruz. Two years earlier, Cruz worked undercover narcotics and was poised for a promotion that would have placed him in a coveted position within the drug organization. The deal went bad. Now he has a new face, a new job, and a new case.

The killer moves through the streets with impunity, identity still unknown. Demands for progress from his superiors, accumulated grief of the victim’s relatives, growing pressure from the public, and elevated stress from his family quietly pull Cruz apart. With no out, the detective moves all in, putting his own head on the line to bait a killer.

Hello. Welcome.

I am TG Wolff, author of the De La Cruz Files series and the forth coming Diamond series. I began writing over ten years ago while living in Cleveland, Ohio and working on a project in Northern Kentucky. With little to fill the time along the I-71 corridor, I began create puzzles, little “whodunits” that kept my mind alert. The little puzzles became short stories and, eventually, full length mysteries. While I am an avid reader of mysteries and thrillers, I love, in capital letters, LOVE, creating mysteries for the reader to solve and enjoy.

In my day job, I am a Civil Engineer. I hold a Bachelor’s from Case Western Reserve University and a Master’s from Cleveland State University. I started in the Transportation field, designing roadways and the water systems that support them. After working nights on my Master’s degree, I began working in the water and wastewater industry, specializing in Clean Water Act compliance. What does that mean? I worked to keep rivers out of the sewers and sewage out of the rivers. While working for private companies, I served people and communities across the Midwest. Many of these became my favorite places and either inspired, or are directly brought into my stories. Currently, I work for one of the largest self-performing General Contractors in the Midwest, helping with the projects that keep our water clean and our communities strong.

So how do I reconcile Civil Engineering with writing mysteries and thrillers? Very nicely, thank you. Seriously, it all comes down to problem solving. As a Civil Engineer, I analyze the problems of our infrastructure, working backwards to figure out what caused them so that they can be resolved. As a mystery writer, I create the whodunits, and then work backwards to create the story that will be read front-to-back. I’m not a cop or a lawyer. My stories aren’t police procedurals or legal thrillers. I’m an Engineer. My stories are about the plot, the mystery. I like to make you think but give you everything you need to solve the problem.
