The Unknown #[nn]

"Chapter One" introduces Catherine Allingham, America's Foremost Detective, whose sharp mind is now battling a terminal illness and the unsettling possibility that her latest breakthrough—connecting Stonehenge to the legend of D.B. Cooper—might be more hallucination than truth. With only six months left, she recruits a quiet, observant bouncer as her assistant for a journey to Austria, where a mysterious machine once designed to measure the human soul vanished without a trace.

In "Chapter Three," Allingham and Doyle track a trail of arcane artifacts—including the Faderbauers' box—to a crumbling sanitarium in Poland, where a mysterious figure known as Kerberos insists he’s uncovered a passage to the afterlife. The air grows thick with secrets as the duo confronts the unsettling truth that some doors, once opened, can’t be closed.

In "Chapter Four," Allingham confronts her most enduring vision—the Chalkfaced Man—standing before what may be the door to the afterlife, while Doyle urges her not to turn Kerberos' key. The line between memory, madness, and the unknown blurs as the weight of the moment presses in.
