PORTSMOUTH -- For those who loved the television show “Unsolved Mysteries,” there is a new series on the Biography Channel that will feature a New Hampshire man who has gained international recognition for his work as a psychic medium and author.

“The uneXplained,” which made its debut last night, uses metaphysical practices to explore human mysteries. Each week, new mystery cases will be presented, clues unraveled and answers revealed by one of several metaphysical experts including psychic detectives, intuitive healers, past-life regression therapists and psychic mediums such as Portsmouth's John Holland.

“I think it is the right time for a show like this to come around, and people will really be interested in it,” said Holland, who filmed his segments in July and August of 2011. “People are ready and are into this genre now, and this is the first thing (of its kind) to come along since 'Unsolved Mysteries' was around.”

Holland, 50, is intimately familiar with shows such as CBS's “Unsolved Mysteries,” which he credits for launching him nationally through his appearance in an episode that explored his abilities as a messenger of the dead.

But Holland — who, for all his otherworldly explorations, appears to remain decidedly down-to-earth — said he harbors no dreams of fame and fortune from his on-screen appearances.

“I have no idea where this may take me, but it is not about being a 'TV star,'” he said. “It is about the work I do and the relief it provides for people with unanswered questions. When parents come to me after losing a child and what I can offer them provides some relief and closure ... well, that is why I do this.”

A native of Dorchester, Mass., Holland said he was born with the natural gift of “knowing things,” adding that it was difficult as a child to know what to do with his gifts. He felt different from his family and peers, he said, and tried to run away from his psychic abilities.

But he received confirmation of those abilities after a near-fatal accident at the age of 30, he said, and, with his unique skills amplified, new abilities surfaced that he could no longer ignore.

“That was the turning point where I had to evaluate my life and what I was doing with it,” he said. “It was then that the dead began showing up with messages and things began to fall into place for me to study this, to learn how to offer more to people than just, 'Mom says hi,' and find out the 'why' to many questions.”

Holland studied metaphysics, spending more than two years training and working in England with some of the country's top psychic mediums. He has since written three books, published by Hay House, on the subject of his abilities as a messenger for those on the “other side” and on how everyone can be more spiritually connected to intuition.

As recognition of his abilities has increased, he said, he tries to keep a low personal profile, but with appearances in episodes of “The uneXplained,” his face may be a bit easier to recognize around the Seacoast.

I typically get someone coming up to me in a store and trying to politely ask if I am who they think I am,” he said. “It's fine, and I don't think this series will change that greatly.”

Holland is scheduled to be in three episodes of “The UneXplained,” on Aug. 25, Sept. 1, and Sept 8. Each episode focuses on individuals faced with an unsolvable problem who have exhausted all traditional means until they turn to Holland to provide some insight and answers. The first of his three episodes features a pair of sisters seeking answers to the mysterious circumstances surrounding their father's sudden death.

The series is the latest offering from executive producer Doug Liman (“The Bourne Trilogy,” “Mr. and Mrs. Smith”) and Russ Stratton. Holland said he was selected for the show after being introduced to Stratton more than two years ago during a mediumship conference at the Omega Institute in Rhinebeck, N.Y., where the producer had gone to scout metaphysical talent for his upcoming series.

Holland said producers found the people featured on the show with real-life mysteries and questions, and said he walked into the room for a reading blind to any of their histories.

“I did not even know their questions, never mind any background,” he said. “This show was really a blessed opportunity for all of us involved. I choose my projects and what I do carefully because I have the utmost respect for this work. This is the perfect fit for my commitment and my abilities.”

In addition to “Unsolved Mysteries” and “The uneXplained,” Holland has appeard on television shows such as “Chronicle” (both the Boston- and New Hampshire-based editions), “Extra,” the A&E special “Mediums: We See Dead People” and the History Channel's “Psychic History: The Waco Story.” He hosts his own show on Hay House Radio every Monday at 3 p.m., and he's been featured on local and nationally syndicated radio programs.

Holland's schedule these days does not allow for much “down” time, with speaking engagements, educational forums, workshops and smaller gatherings around the country filling his schedule. This November, he'll also take part in “spirit connections” cruise to the Caribbean as one of the featured speakers, along with James Van Praagh, one of the world's best-known — and most controversial — mediums.
