Detective Inspector Phillip Devlin of Scotland Yard is having problems of his own. Having fallen for his younger constable, Freddie Collins, Devlin finds that leading his double life is often more complicated than he’d originally thought. But for now he must set aside his worries, as he is called on once more to catch a killer and expose the perpetrator of this latest threat to his beloved city. He must use every resource at his disposal, both inside the law and out, to halt a string of murders the likes of which London hasn’t seen since the days of Saucy Jack. But what Inspector Devlin will soon learn is that murder is not necessarily the greatest of sins . . . and some truths are better left undiscovered.
