A snowstorm seals off an aging estate. A priceless coffer goes missing. And every guest has a reason to want it gone.

Retired detective Alistair Greaves planned a quiet Christmas dinner; a final act of hospitality before selling the manor he's kept shuttered for years. But when the storm cuts them off and a priceless, long-buried coffer vanishes, Greaves realizes the gathering was never about dinner. Every guest carries a motive, every corridor hides a secret, and every sound in the walls might signal a new betrayal.

As tapping patterns echo through the house and old rivalries ignite, Greaves must outthink thieves, traitors, and infiltrators who know the manor's secrets even better than he does. What's inside the coffer is no jewel, no heirloom, but a secret powerful enough to resurrect enemies he thought were long gone.

Before dawn, the coffer will be found, the truth will be burned or bled for, and only those who can decipher the silent signals will leave the house alive.
