This detective series doesn't start off with very interesting cases, but the cases do get more intriguing after one gets past the first few episodes.

As a detective series, it is at least passable. It doesn't try too hard to do something original or have really unexpected twists. However, most of the cases are at least interesting enough to follow. A couple of cases (the teenage killer and the cult leader cases) start from early in the series, perhaps in unsophisticated attempt at creating a sense of connection. However, the cuts to the teenage killer and the cult leader can be somewhat disorienting without really being suspenseful. (On the other hand, especially for the case of the cult leader, it may be difficult to finish the cases quickly if they crop up only in the later episodes.)

The series has a rather nice old-school feel in terms of the setting. The Sherlock Holmes and Watson references add on to this feel. The series is a sort of homage to Doyle's Sherlock Holmes, complete with an equivalent of Moriarty. The equivalent of the Moriarty in the cult leader, however, may just be a little too much of a challenge for one's suspension of disbelief. The effect that she has on people seems a tad exaggerated, and we also don't really know what the cult is all about besides some references to a belief in some utopia.

The bromance between Detective Himura and the novelist, Alice / Arisu, is endearing despite not being the focus most of the time. At some points, it even has hints of romance rather than bromance (though the lines are often blur in other series anyway)--in one scene, the landlady even hints to everyone that they should leave Himura and Alice alone and not play gooseberry, and no one seems surprised. The real surprise is that the series actually does bromance better than some series that bait BL fans only to turn the characters' relationships into rather bland instances of bromance.

This series isn't groundbreaking contribution to the detective/whodunit genre, but it isn't disappointing either.
