Solving the puzzle could be the last thing he does… PI Charlie Dodge knows what it’s like to have something important disappear. His wife, Annie, suffers from early-onset Alzheimer’s, causing her to remember little of the life she shared with her husband. Charlie has devoted his career to saving what he can—missing people, threatened lives. But when prominent Denver multimillionaire Carter Dunleavy vanishes without a trace, Charlie and his assistant, Wyrick, discover missing doesn’t always mean gone. It turns out Carter didn’t vanish after all—he’s gone into hiding. Someone in his inner circle wants him dead and now Carter needs Charlie to expose the culprit before the Dunleavy empire spirals into ruin. But with a tangled web of suspects looking to silence Charlie’s investigation, he’ll have to find Carter’s would-be killer and fast, before the traitor can finish the job.

The clock is ticking… When Charlie Dodge gets a phone call from a frantic woman stating her daughter has been kidnapped by her ex-husband and taken into a cult called Fourth Dimension, he takes the case without hesitation. The cult’s rumored purpose is to gather men with psychic abilities with the goal of breeding a race of people who have supernatural powers. Once accepted into the cult, men are given a young girl to marry in exchange for one of their own daughters. The FBI has been monitoring the cult’s activities, but Charlie and his assistant, Wyrick, aren’t bound by the same rules as the feds. They head to the mountains of West Virginia to infiltrate the cult’s compound. The lives of children are at stake, and Charlie and Wyrick will risk everything to destroy the cult and its leader—no matter the cost—because this case is personal.

He has nothing and everything to lose… When a seventeen-year-old boy goes missing while camping with his buddies in the Chisos Mountains in Big Bend, the case is right up PI Charlie Dodge’s alley. Charlie’s reputation for finding missing people—especially missing kids—is unparalleled. Unfortunately, trouble seems to be equally good at finding him. Charlie’s still in the thick of it when bad news arrives regarding his wife, Annie, whose early onset Alzheimer’s is causing her to slip further and further away. The timing couldn’t be worse. Thankfully, Charlie’s ride-or-die assistant, Wyrick, has his back. But when Universal Theorem, the shadowy and elusive organization from Wyrick’s past, escalates its deadly threats against her, it pushes both partners past their breaking points. Finding people is one thing; now Charlie will have to fight to hold on to everyone he holds dear.

Charlie Dodge may be down, but he’s most definitely not out. He’s still reeling after a series of earth-shattering events, so when a desperate woman hires Dodge Investigations to find her missing sister, the head-scratcher of a case is exactly the distraction Charlie and his steadfast partner, Wyrick, need. Two weeks prior, Rachel Dean disappeared without a trace from her locked-from-the-inside Dallas apartment, and every possible trail has gone cold. Grappling with the fallout of her efforts to dismantle the shadowy organization Universal Theorem, Wyrick throws herself into her investigative work. Charlie knows his partner can handle herself, but when she uncovers a past connection that paints a target on her back, the threat of losing her hits Charlie hard. There’s nothing he wouldn’t do to keep Wyrick safe, but with the clock ticking on a victim they’ve yet to find, it’s only a matter of time before the cold-blooded killer leads them to a deadly end.
