Someone to Save You by Paul Pilkington. Published by Thomas & Mercer

Sam is returning home from the bittersweet celebration of what would have been his murdered sister’s 30th birthday when he helps avert a tragedy. A woman, intent on ending her life, has parked her car with her children inside on a train track. Sam pulls the family to safety, but instead of being hailed a hero, he’s greeted with suspicion. The police say the story doesn’t add up and Sam gets caught up in organized crime at the same time his sister’s killer, and his former best friend is being released from jail. Marcus swears he’s innocent and wants Sam’s help proving his innocence by finding the real killer. Like all Pilkington’s books, this is a well crafted page turner
