Book Summary: Gah! It’s a Double Run!
The Setup: Following the cold, clinical exit of his girlfriend—who left him with nothing but a frosty "Ciao, see you soon"—Leo, a "recycled" Corporal and tactical geologist, realizes his life has been a carefully constructed lie. To find the truth, he reunites with Ergon Schaswaski and a "band of merry men" (a group of discarded, alcoholic veterans) to trace his origins back to the Bassingbourne Training Ground.
The Journey: The crew uncovers the "Null of Wish," a shadowy military-industrial organization that treats human lives like cards in a high-stakes game of Rummy. Leo discovers that his entire career—the "Geologist’s Gambit"—was a stress test conducted by the organization. He tracks the conspiracy from a subterranean vault known as the K-hole to a final, desperate infiltration of the Bassingbourne archives via the "Black Pipe," a silt-clogged drainage tunnel.
The Betrayal: Inside the command center, Leo confronts his handler, "C" (the woman who left him), only to find out she was a "surveyor" mapping his psychological fault lines. They are met with a digital broadcast from The Director, revealed to be Leo’s old Sergeant-Major, who claims the Null of Wish is a necessary evil to "clear the deadwood" of the nation.
The Twist: In a final, guttural confrontation at a secluded Cornish villa, Leo faces the ultimate "Gah!" moment. He isn't just a victim; he is a biological redundancy. He meets The Original Leo, a high-ranking architect of the Null of Wish. The "Corporal" version of Leo was merely a field-tested clone designed to be the "purge"—a weapon meant to destroy the organization's liabilities and reset the deck.
The Ending: As the "Original" activates a kill-switch, Leo realized that his sense of "making amends" was just part of his programming. The book ends with the "Original" walking away, leaving the Corporal to be reclaimed by the silt, setting the stage for a final showdown in the next installment.
