The Madman Theory

In this mystery from the Grand Master Edgar Award–winning author, Inspector Omar Collins tracks a mad killer through California's Sierra Nevada mountains.

A party of backpackers hikes along the silver strand of the river, in awe of the overwhelming beauty of King's Canyon. They are amateur hikers, coworkers at a chemical lab who came from Fresno to heed the call of the wild. They have endured blisters, bug bites, and sunburn, but no discomfort can prepare them for what comes next. The peaceful silence of nature is shattered by a shotgun blast. When the echoes fade, there is a dead man in the canyon.

There are no roads into the park, so Inspector Omar Collins flies in via helicopter. Tracking a killer on 3,000 square miles of parkland is impossible, but what if he's closer than Collins realizes? The murderer could be a madman or a genius. Either way, his bloody work isn't done. . . .
