Who doesn’t love a good Sherlock Holmes retelling? Now make it diverse, with wonderful loveable characters, an alien world, a dash of humour, and a lot of cosy vibes. And did I mention the space elves? Definitely not just for fans of the infamous detective duo, but everyone who enjoys cosy sci- fi and mysteries.

A Study in Black Brew is a Sherlockian mystery with a fresh scifi slant that enlivens a classic while paying homage to spirit of the original. A must read for fans of Conan Doyle who yearn for a modern twist.

An alien Sherlock Holmes lets Howalt explore new aspects of the well-known characters. The relationship between the retired chemist Kellieth, who has a respiratory dysfunction, and the brilliant but also somewhat annoying and insensitive detective Raithan unfolds convincingly. Through Kellieth’s narration we experience the struggle of living with a disability that is physically straining as well as a social problem because the wendek communicate their emotions through scent. Like Howalt’s Colibri Investigations books it’s a soft SF cozy murder mystery with a lot of seriousness to it. A nice cup of black brew, well rounded but still sharp.
