Christopher Morris believes Lucy Letby has been the victim of a miscarriage of justice, and that her guilty verdict is not beyond reasonable doubt. He is not the only one.Ever since the nurse was condemned to fifteen life sentences, highly-regarded professionals in their fields have gone on record to raise concerns about the evidence used to convict her. The science behind how her victims died, the reliance on circumstantial evidence, and the interpretation of the statistics used against Lucy Letby are all being questioned. Controversially, the defence did not call an expert witness to challenge the medical evidence presented by the prosecution. Nobody, except her lawyers, knows why. In a quest to find out if he is correct, the author has interviewed scores of those experts. He has also pored over the thousands of documents submitted to the Thirlwall Inquiry, which is examining what went wrong at the Countess of Chester Hospital, as well as the transcripts of the trial. He has pulled this vast amount of information together into an engrossing journey through the uncertainties many feel undermine the conviction of Lucy Letby.The answer matters for us all, as it raises serious questions about whether our justice system really does seek the truth.
