The Mystical Mister Kay

Miss Cassidy #3

by Meihan Boey

Winner of the 2025 Epigram Books Fiction Prize

The final gripping chapter in the saga of Miss Cassidy.

The truth is out there. And somewhere, so is Miss Cassidy.

The Mystical Mister Kay, a ghost-seer from Singapore, arrives in the English city of Tolwich in search of his friend Miss Cassidy. But his investigation takes a darker turn: a princess is found dead, a cult-like fashion house holds the city in its grip, and a seminary for Asian royals hides secrets no one dares name. As gods from Ancient Greece and Asia slip into the mortal world, Mr Kay is pulled into a mystery that spans continents and mythologies—one that may bring him closer to Miss Cassidy, or destroy him trying.

3.4☆

Though I didn't read the first 2 books, the first half of this book explained a little further on what went down previously and how it got to this current narrative. Though it was a bit long, for that I am grateful.

While this was a wild fantasy ride, the bits and pieces of Singapore that were weaved in was delightful. Though I just wonder at times, for the expressions in Malay, would non-Malay readers understand?

Frankly I found it a bit difficult to piece the story together with such an array of characters. However, towards the end, the story wrapped up quite well so it does feel like I had closure. Overall a good read, despite taking about a week to process this.

4.5 🌟 fat, satisfying, and easier to follow than the previous two books in the series. After a lifetime of reading about ghosts and other invasions in SEA by non SEAsians, it is so wonderful to read about the inverse, mobile and sulky and agentic. The series occupies the same spiritual trajectory as Zen Cho’s Spirits Abroad imo.

i love this series so much it’s kinda bittersweet and sad that it has reached its conclusion. but one can hope for more novels of this nature - where myths and legends of different cultures across the world intersect.

Meihan Boey’s Miss Cassidy series and Ovidia Yu’s Crown Colony series are the wittiest most entertaining most subversive examples of the empire writes back.

Characters were fun, but the overabundance of gods and god-like beings that had decisive impact on the story was a bit too much for me.
