THEY KNOW HE IS INNOCENT.
THEY STILL WANT HIM DEAD.
Edward Ormsby knows how buildings stand. He needs to know what this one is hiding.
Convicted of an archivist's murder, the structural engineer awaits execution at Brannock State Penitentiary. The date is December 24. He has twenty-four days to prove the state condemned the wrong man.
Then a guard notices that the murder weapon weighs more on its intake form than it did in court.
Before he can explain the difference, he is killed.
A warning hidden in a paperback reaches Edward. It points him toward his family's old structural plans and the prison's foundations. His grandfather helped build parts of Brannock. He also left records that powerful men cannot afford to have found.
Following those plans, Edward begins tracing a secret history of missing inmates. Finding the evidence means relying on people whose pasts he barely knows. An apparent rescue could lead him directly to the men who framed him.
Even if he reaches the buried records, he still has to get them outside before his execution.
Rachel Kozlov's The Prison Beneath is a Christmas mystery advent calendar told as one continuous novel, with twenty-four dated chapters. Read a chapter each day from December 1 to Christmas Eve, or follow the investigation straight through.
If you enjoy mysteries where a small discrepancy can undo an official story, this novel gives you evidence to question as Edward works out whom he can trust.
Make this your December mystery. Begin with Day One, and see who you trust by Christmas Eve.
