But the passionate and brilliant Home Office pathologist Dr Lennox Collins and his vivacious young secretary Molly Cooper have their doubts. Employing ground-breaking forensic techniques, can Lennox and Molly save a seemingly innocent man from the gallows or is there more to these murders than meets the eye?
