Brian Cox and Robin Ince are joined by comedian Susan Calman, Prof Sue Black and Dr Julia Shaw as they invent Infinite Monkey Cluedo, and discover whether they can commit the perfect murder, or whether the latest forensic science will always be able to piece the clues together. They reveal whether the perfect crime or perfect criminal really exists and how we might spot them, and how the latest forensic techniques have transformed even decades-old murder cases. The panel also discuss how the courtroom has changed with the development of ever-more advanced forensic techniques, but also where the weakness in the science might lie.
