The Measurement Problem
A high-concept near-future science fiction thriller told in a noir style.
Metropolitan Police detective Lewis Drake is shot dead, a bad start to the day. He finishes his macchiato and departs to begin his shift.
It gets worse when the murder case he is assigned involves one of the entangled, those who have learned to live in the many worlds of the quantum multiverse without losing their minds. Lewis despises the entangled and hates the drugs they take to join their alternate selves.
The case expands into a complex web of murder, corruption, conspiracy and espionage with the entangled gang leader Vidmar at its centre. Lewis’s sister Alice knows all the answers but she is lost in the chaos of a multitude of realities. Only if Lewis overcomes his prejudices and takes the black capsule that will open his mind to other lives will he be able to solve the murders, find the elusive Erica, and protect Alice.

An impressive novel. Whitmarsh manages plot a satisfying mystery that takes us across five dimensions! It’s proper science fiction, interrogating how our world and society would be if we had access to alternative versions of ourselves predicted by the many worlds theory. Whitmarsh navigates this skilfully, creating a believable world and a whole bunch of cool consequences that flow it. He ties it up in puzzle that keeps you guessing all the way to the last page. I look forward to more.

I really enjoyed this. The use of the idea of endlessly diverging universes was clear and consistent and central to the story rather than the background to it. Proper science fiction, not just throwing in some magical technology to fix a plot hole.
The story was interesting and the main character engaging. The plot had lots of interesting puzzles and kept you guessing until the end.

This is the kind of book that has you gripped for the entire ride, and then resonating with ideas and thoughts and ideas for days afterwards... which is only fitting! I hope that this is the start of a whole new genre: "Quantum Noir". Highly recommended!
