Dead Ringer. Partners in Crime, #5

Jack and Jamie are called to a hundred-year-old murder scene where they find two skeletons, and one ghost-Patrick Kennedy. Called to an excavation site in the subway tunnels under the city, Jack and Jamie meet Jamie's great-grand uncle who'd been murdered in nineteen twenty-one. What do you do with a ghost who is suddenly a century in the future -who likes arguing with the TV?"I think unnecessary drama should be a valid murder defense, " Jamie replied.
"I've tried to explain to him that the TV characters can't hear him, but he doesn't understand." Cultural difference make things difficult, then throw in the fact he's family and Jamie's ready to strangle Patrick, if he wasn't already dead. When a second case lands in their lap, with another ghost seeking justice, the complications add up. A young woman is murdered in her home and the connections between the two cases are building with every new bit of information they find.
Murder, arson, and stolen legacies from the 1920s are now relevant, a century later. Power and politics are again behind the threats to Jack, Jamie, and the people they love. Will they be able to right a century-old wrong and still get justice for a current crime?
