After her husband's death, a small-town accountant finds herself drowning in paperwork and grief when she discovers a leather-bound ledger hidden in his office safe-one with no record in any legitimate business account. The entries are meticulously coded, each one corresponding to a person reported missing over the past decade. As she begins to decrypt the cipher, the coded transactions paint a horrifying picture: dates, locations, and amounts of money that align with disappearances across three counties. Her hands shake as she realizes that the man she slept beside every night may have been orchestrating something unspeakable, and she was too close to see it-or perhaps, too willing not to.

But the ledger's real horror isn't in the past; someone is still watching her. Strange visits from unfamiliar people asking innocent questions, her home subtly disturbed, her movements tracked. As she digs deeper into the coded entries, she uncovers a network far larger than one man, and her investigation threatens to expose people with every reason to want her silent. Torn between her need for truth and her survival instinct, she must navigate a web of complicity and corruption while racing to decode the final entries-entries that suggest her husband may not have been the architect of these crimes, but merely a keeper of dangerous secrets. And someone wants those secrets buried with him.
