The best science fiction murder mysteries

What I love about a murder mystery is joining the dots, connecting all the different elements together.

Dirk Gently’s Holistic Detective Agency is all about connections. Whether it is the aliens who’ve been secretly living on Earth for millions of years; or the ghost of the murder victim trying to leave a message on his sister’s phone; or Richard, the book’s hero, attempting, with the "help" of the ever-unreliable Dirk, to figure out what is going on here and why.

I was simply lost in the convolutions of a plot that also involves time travel and the highly vexing question of how a sofa came to be impossibly stuck on a landing. It’s ALL connected, and the solution makes sense of (nearly) everything.

In my view, a great murder mystery should have a lot of possibilities, and science fiction just adds deeper layers of intrigue, and this is what The City and The City has in spades – literal layers and intrigue.

Here, two cities exist in the same place, yet the citizens of each one must ignore the citizens of the other. It is a crime to notice the citizens of the other city. When a murder occurs and our detective investigates, he only has jurisdiction in one city.

But what really blew my mind about this book was that, though it is science fiction, there is no physical or scientific reason that the cities are separate and occupy the same place. The division is only in the minds of the inhabitants!

I love how, years after my first reading, Zoo City still haunts me.

It’s set in South Africa, where Zinzi December has been ‘animalled’, after causing the death of her brother. All humans guilty of a death are magically attached to an animal, which also gives them psychic powers.

In Zinzi’s case, the animal is a sloth she can’t be separated from, also giving her the ability to find things. When she is asked to track down a missing woman, her quest explores the dark side of this world and sends this former drug addict on a violent and dangerous path to redemption.

This Arthur C Clarke Award-winning book is a dizzying read. I loved feeling as lost and uncertain as Zinzi the deeper into trouble the mystery sends her.

A brilliant science fictional idea changes everything about the world, and in Tade Thompson’s Arthur C Clarke Award-winning Rosewater, where an alien dome has appeared in Nigeria and opens once a year to heal the sick, the world has been thrown dangerously off-kilter.

The murder-mystery is not a conventional one as our hero Kaaro, a human sensitive created by this alien intrusion and now government agent, is trying to figure out why those like him are suddenly dying. There are many strange science-fictional ideas driving this book, but it is Kaaro – a former thief trying his best to do good in difficult circumstances – that gives this book its wonderful heart.

I believed in and rooted for him even though he doesn’t ever seem to believe in himself.

I love the hooky concept at this book’s heart: Mahit Dzmare is the new Lsel ambassador sent to the heart of the enormous Teixcalaanli galactic empire to maintain her tiny space station’s independence; but on arrival, she discovers her predecessor was murdered.

Now, she must not only act the diplomat, but she must also solve the murder without offending the very empire that at any moment could swallow her people whole.

The intricate-but-lightly-done world-building further helps bring this book to stunning life as Mahit walks a wobbly tightrope between asking difficult questions and preventing her very dangerous hosts from taking offence even as the politics take a dark turn, which threatens her life and everything she holds dear.
