Meet Thomas Coyle, a leading forensic scientist with a background investigating murder for Scotland Yard and identifying bodies after global disasters like the Boxing Day tsunami and the Christchurch earthquake. He’ll be “interrogated” by ex-coppers and authors of the best-selling Bookshop Detectives series, Gareth and Louise Ward, about his book The Dead Speak.

Take a walk around a crime scene, discover the importance of the minutest evidence and find out how victims and sometimes their killers are identified.
