Causes Unknown — Leslie Alan Horvitz

It just didn't make sense. When Michael Friedlander heard how his brother had died, he couldn't accept it. So he started to look for his own answers. But every lie he uncovered or secret he exposed simply drew him deeper and deeper into a chain of cover-ups that has led him at last to the New York City Medical Examiner's office....

The ME's office is just one part of a widespread conspiracy. Shadowy figures have created a hidden power structure involving the city's most trusted agencies. Michael has come too close to a truth far more dangerous than he can imagine. If he isn't able to discover the conspiracy's final secret, he will become its latest victim.
