"Beyond the boundaries of ordinary life, there is another world that lies just outside of town, where places have no names." That's Investigation Discovery's introduction to "Murder Comes to Town," a true-crime series that reveals what can happen in solitary and desolate places. Hourlong episodes feature gripping tales of betrayal and murder buttressed by re-enactments and interviews with friends, family, and neighbors of the deceased, plus law enforcement personnel.

Powerfully emotional stories tell of people who have been targets of compulsive stalkers. According to the Centers for Disease Control and Prevention, more than 6 million people in the U.S. are stalked each year, and in most instances, the stalker is someone the victim already knows. The series' hourlong episodes dramatize actual cases through visceral re-enactments and pointed testimony of victims, family members and law enforcement authorities, revealing what happens when stalkers can't have what -- or who -- they want, and stop at nothing to ensure that no one else can either. The chilling accounts probe the mechanics of an obsessive mind and the devastating impact of delusion.

While most killers act alone, there's another type of murder that happens less frequently yet still produces horrific consequences. That's when people decide to kill as a group. This Investigation Discovery series details true-crime cases that involve victims who have been savagely murdered by their own friends. Stylized re-enactments featuring first-person accounts from law enforcement personnel and friends and family of the victims accompany each story.

Like a pane of glass cracking in all directions before shattering, the impact of a single crime can create ripple effects that forever alter multiple lives. This Investigation Discovery series unravels actual homicide cases to explore how the past continues to haunt the present for those involved -- loved ones, witnesses, and law enforcement. Each episode is structured around three distinct perspectives of the same crime, and as viewers learn different details by way of first-person interviews and stylized re-enactments, stories, which at first seem random, slowly start to intertwine.

Secrets are never safe from seeing the light of day, even ones that are housed with skeletons and buried six feet under. Those, especially, are of interest to law enforcement personnel, who unearth long-thought gone secrets that eventually help unravel murder mysteries. The details are described in hourlong episodes of "Grave Secrets," with re-enactments providing the meat and potatoes of each true-crime story, and interviews with victims' family, friends, and investigators adding context.

Transporting viewers into what Investigation Discovery calls "a vortex of dark mystery and psychological terror," the docuseries "Dead Silent" delves into actual stories of crimes set in desolate locations. Hourlong episodes portray just how dark and dreary the great outdoors can be when a person is deep in the woods, inside an abandoned house, or along the shores of a sleepy lake, and every snap of a twig and unidentified rustle can be a sign of danger. ID's signature storytelling interweaves commentary from local authorities, true-crime experts, and psychologists, plus first-person accounts from survivors of these crimes.

"Love the Way You Lie" -- based on the best-selling 2012 novel "Gone Girl" -- presents two versions of actual murder cases and lets viewers decide which one to believe. Filmed in a classic "he said, she said style", each hourlong episode follows a highly disputable crime from dueling perspectives -- those who believe the suspect is guilty, and those who proclaim the suspect's innocence -- and features commentary from local authorities and true-crime experts, as well as first-person accounts from friends and families of the victims and suspects.

"Betrayed" reveals chilling stories of chasing the American dream and how the veneer can dramatically crumble, ending in murder at the hands of a trusted family member, co-worker, lover, or friend. The cases of deception are told through the lens of the fictionalized, first-person perspectives of the victims. As investigators, family, and friends peel back the layers and facts of each case, the otherworldly narrator already knows where the trail ends. The narrator guides viewers through various relationships, raising suspicions about who will commit the ultimate betrayal.

No matter how complicated or seemingly straightforward a murder investigation may be, experienced law enforcement personnel always employ tried and tested methods to catch their prey. Documenting witness statements, pouring over forensic reports and crime scene photos, nailing down the timeline, and keeping an open mind about the causes and possible perpetrators of a crime are essential to an investigator's success. "Six Degrees of Murder" delves into another essential element that could be the difference between a solved case and a cold one. Featuring stylized re-enactments, each hourlong episode details how investigators untangled a complicated web of relationships before cracking a murder case.

Chilling scenarios unfold in this true-crime series, which tells actual stories of people who shared their lives with loved ones who became killers. Each hourlong episode puts viewers in the shoes of the loved one, who first notices that something is amiss, interprets the puzzling signs and clues, and eventually comes face-to-face with the horrible truth: that the person has a very dark side. Exclusive interviews and firsthand accounts of the critical moments leading up to the vicious acts showcase devastating, often undiscussed consequences on the people who have nurtured, loved and raised a murderer.
