Raising an army of ghosts may not be a traditional method for investigating crimes, but Robert, Clothilde, and Captain Evian believe it's their last hope in the search for justice. The first of many obstacles? To free the ghosts from their cemeteries, they need Commander Diome's signature on the exhumation orders. This means convincing Evian's no-nonsense boss that ghosts do indeed exist. In this final installment of the Ghost Detective novel series, Robert and Clothilde close in on the group that had them murdered thirty years ago. Will they finally find the closure they need to move on?
