A good man's work is never done... It should have been a quiet life for Callum MacBain. Project T was supposed to be done for, his actions had been redeemed, and he'd survived to retirement. Add on to that a lucrative book deal about his life, and MacBain should have been happy... should have been satisfied... But for a man who sought justice his whole life, it's not enough. But when his old partner Fletcher asks for MacBain's help with a horrific murder case, he jumps at the chance to be his old self again. It's time for Callum MacBain's final case. Hopefully, he'll live to see the end of it.
