The Colorado Kid

The Colorado Kid is a mystery novel by American writer Stephen King, published by the Hard Case Crime imprint in 2005. The book was initially issued in one paperback-only edition by the specialty crime and mystery publishing house. King's next novel for Hard Case Crime was "Joyland", which was published in June 2013. Hard Case Crime reissued "The Colorado Kid" in an illustrated paperback edition in May 2019.
The third-person narrative concerns the investigation of the body of an unidentified man found on a tiny island off the coast of Maine. Lacking any identification or obvious clues, the case reaches nothing but repeated dead ends. Over a year later the man is identified, but all further important questions remain unanswered. The two-person staff of the island newspaper maintain a longstanding fascination with the case, and twenty-five years later use the mysterious tale to ply the friendship and test the investigative mettle of a post-graduate intern rookie reporter. 
A television series loosely inspired by "The Colorado Kid", titled "Haven", aired on Syfy from July 2010 to December 2015.
Plot summary.
Opening "in medias res" as the news staff of "The Weekly Islander" pays for lunch at a restaurant, editor Dave Bowie and founder Vince Teague test young intern Stephanie McCann's powers of deduction regarding their unorthodox tipping procedure. She impresses them by discerning that the restaurant management pools all the tips and splits them equally among the staff, while Dave and Vince want to leave an especially large tip earmarked for their waitress who has fallen on hard times. They discuss some local unsolved crimes and oddities, which have gained circulation in mainland newspapers as far away as Boston during the traditional Halloween season interest in such tales. The friendly assessment becomes more intense as the elderly island natives and Stephanie return to the office, and she asks if the veteran reporters have "ever come across a real unexplained mystery". Dave and Vince take turns recounting a strange incident and investigation.
On April 24, 1980, two teenagers stumbled across a man's body, early in the morning. Slumped against a trash can, and carrying no identification, the body bore no clear indicators of foul play. Cause of death was determined to be asphyxiation, as a large chunk of flesh was extracted from the victim's throat. Every potential clue leads to small revelations, but bigger mysteries. Though the investigation is lightly bungled, everything seems inexplicable, from how the fish-dinner stomach contents could line up with his ferry boat crossing, to the single Russian coin in his pocket, and the pack of cigarettes missing one cigarette when the autopsy indicated he was not a smoker.
More than a year later, thanks to a sharp-eyed rookie spotting an out-of-state cigarette tax stamp among the man's personal effects, the John Doe becomes known as The Colorado Kid. Eventually the man's identity is traced: James Cogan of Nederland, Colorado. He was a commercial artist living a normal middle-class life with his wife, last seen at a seemingly average workday before inexplicably disappearing. There was no hint of money troubles, adultery, drug addiction or mental illness -- the factors normally associated with someone leaving home so suddenly. Everyone involved with the case is at a loss as to how or why the man could have traveled over 2000 miles (3000 km) in the five hours between when he was last sighted in Colorado and first sighted in Maine, when there was at the time no direct airline flight to account for his arrival. 
In the "Weekly Islander" offices, the three friends, old and new, ferret out all the answers they can from the facts of the 25-year-old investigation, then speculate on what might have happened, and meditate on the nature of true mysteries. Despite the lack of clear evidence, Dave and Vince hypothesize the Colorado Kid was murdered. He probably flew to Maine on a chartered jet under an uncertain but pressing emergency and carried the Colorado cigarettes as a clue to his origins should he come to harm. Though Dave and Vince shared other unsolved crimes and oddities with outsiders, they have kept the Colorado Kid a secret due to their belief that a big-town newspaper or glossy travel magazine would tell the story inaccurately by wanting to provide resolution to the account that stubbornly defied a clean culmination. They inform Stephanie that while they were "the last people alive who know the whole thing", having heard the tale of The Colorado Kid, "Now there's you, Steffi." The warm proclamation seems to signal the young woman's final approval by the old guard of the "Islander".
King's comments about a clue.
King noted on his personal website on October 7, 2005 that an apparent research error regarding the rise of Seattle, Washington-based Starbucks Coffee may hold other implications, tying the book's story to the same shared universe of many of his other novels: "The review of "The Colorado Kid" in today’s issue of today's "USA Today" mentions that there was no Starbucks in Denver in 1980. Don’t assume that’s a mistake on my part. The constant readers of the "Dark Tower" series may realize that is not necessarily a continuity error, but a clue."
