When an elderly man is found murdered in his basement, an investigator has no leads except a photograph of a young girl’s grave. The investigator discovers that, many years ago, the old man was accused, though not convicted, of horrible crimes. Did the man’s past come back to haunt him? As the investigator reopens the cold case, he follows a trail of unusual forensic evidence, uncovering secrets much larger than one man’s murder – and with clues knit into the genetic bloodline of an entire country.
