The weather turns to spring, and Charlie faces a pair of puzzles. Against Charlie’s better judgment Ron, her PI partner, takes a cheating-spouse case that turns into a comedy of errors involving a star football player and his wife’s petty vengeance. Meanwhile, Charlie’s neighbor Elsa has a bad feeling about a family up the street. Is it a case of the neighborhood busybody having too much time on her hands, or is there truly something sinister happening with twin teen girls who’ve been left with too much money and not enough supervision? 

Charlie Parker and her husband Drake Langston accept a job with Gold Trail Adventures in Skagway, Alaska, flying visitors by helicopter to remote cabin sites to experience the outdoor lifestyle and seek their fortunes. It isn't long before one of the guests finds a set of bones in an old mine, remains that date back decades.

Charlie and Drake are working a helicopter job in rural Maine when a man approaches and asks for their help. At first glance, it seems he's just an old man who needs to get to his son's remote cabin in the woods. But the cabin holds more secrets than Fergus McNab will admit, and it isn't until Charlie returns to Albuquerque that she discovers they may have just aided and abetted a criminal who has escaped the law back home. The secrets get twistier, the more she looks into the 10-year-old case where Rory McNab, facing a life in prison, seemed to vanish from the reach of the law.

It's Christmas in Albuquerque; Charlie and family are ready for a quiet holiday at home. But right away, her hopes fade when Charlie's brother and PI business partner, Ron, brings in two new cases, one of which made national headlines. Five years earlier, with the tide of media attention and public sentiment against her, Tali Donovan was acquitted of killing her two children and went into hiding. Now, on the anniversary of the children's disappearance, their father wants answers.

Charlie receives an enigmatic letter from her namesake aunt, her father's estranged sister, whom she's never met. Soon she's off to England. In the charming medieval Suffolk town of Bury St. Edmunds it isn’t only slightly eccentric Aunt Louisa’s beliefs in the occult or her spooky "haunted sites" tours that pique Charlie’s interest. When a friend of Louisa's is plagued by a series of pranks, Charlie and Louisa offer to find out what's behind them. But Charlie soon discovers that something sinister is brewing and she finds herself drawn into an investigation of crimes that are far too real.
