Proving that sometimes it really does take two to tango, this hardcover, full-color edition is a collection of true-life stories which show the very worst that can happen when two evil individuals hook up with each other. Serial killers and sadistic sex murderers are, by nature, solitary predators who keep their sordid secret to themselves until painstaking detective work, profiling, forensics or sheer luck leads to their capture and conviction. However, an increasing number of these brutal crimes are being perpetrated by two or more individuals acting together. Together they are twice as dangerous, twice as deadly. By working in tandem they can cover each other's tracks, subdue their struggling victims and dispose of bodies more easily. What makes such seemingly ordinary individuals hunt together, feeding off each other's addiction to cruelty? Is it a power trip? Do they need the approval of an admiring partner? Or is it just tainted love spiraling out of control? Fully illustrated with black and white photographs and page decorations, this collection of horror stories is a necessary addition to any true-crime fan's library. It warms the human heart to see a couple in love. Unless, of course, the couple is one of the deadly duos profiled in this book.
