When Chloe Macbeth begins to receive threatening letters, she has no doubt who is behind them: David Jarrett, languishing in jail for the murder of his adoptive parents. Jarrett is convinced that Chloe - out on parole following a conviction for GBH - is the real killer. But have the previous crimes in Jarrett's past finally caught up with him? When a local businessman is stabbed to death in a street altercation, DCI Grace Swan and DS Terry Horton find themselves pitted against the most dangerous criminal they have ever encountered: the Mannikin Killer. Can they track him down before he kills again? Find out in 'I Know It Was You', the second book in the DCI Grace Swan Thrillers series by Giles Ekins. This book contains graphic violence and some strong language, and is not recommended for readers under the age of 18.
