The Blackwell Deception is a welcome addition to one of the most enjoyable adventure game series ever made. It can sometimes become unclear what you should be doing next and missing a clue can often result in aimless wandering – but for the most part the story unravels at a brisk clip that continually excites and delights. Yet the real reason you should play The Blackwell Deception is for Rosa and Joey – an adventure gaming duo made in heaven. A polished, engaging adventure that, although not short by any means, is over far too soon. Roll on Blackwell number five!
