This is excellent detective series with a relishable and well-executed concept and a few obvious but forgivable defects.
The rather long prologues in several episodes are predetermined by the setting that neither of the two loosely-connected protagonists is a professional detective. One being an unattractive and middle-aged (appearing to be) female journalist writer focusing her enterprise on correcting legal injustices and the other an immature-looking magician assistant, or rather, the creative consultant of a famous magician, whose nerdiness isn't socially impotent enough of that of Moss (The IT Crowd) and whose abstract mind isn't emotionless enough of that of Sherlock Holmes, a fairly large chunk of an episode could be devoted to introducing the truth seekers to the case as seamlessly as possible.
Despite the feeling of detachment (at first) and the lack of 'professionalism' evoked by the aforementioned setting, an atmosphere of 'an ongoing everyday life integrated with delicately crafted tricks for hideous purposes' is created, which, according to my pathetic knowledge of detective story, is innovative to a certain degree. The cornerstone of nearly all cases is 'trick', and the delicacy of the setting of crime scenes manifests the beauty of magic. That which appears to be confused and impossible to achieve could, through reasoning (deciphering the hard work involved in), be unraveled and manifest its core which is sometimes too simple to be astonished at.
Jump scares (most of which with no scary results) and British humor (if it is called such) are scattered throughout the series, and yet the affection development line of the two protagonists doesn't interest me very much; alongside the overall OK acting of actors, the series still deserves a 4/5.
