In the Blink of an Eye

A Time-Consuming Mystery

by Yoav Blum

A sealed room, a dead physicist, and a machine designed to test the boundaries of time form the foundation of In the Blink of an Eye by Yoav Blum. It’s a premise that naturally invites questions about truth, sequence, and the hidden forces surrounding a single moment.

When Professor Yonatan Brand is found dead in his locked study, the circumstances appear impossible. Brand devoted his life to understanding the mechanics and dangers of time itself, carefully mapping out paradoxes and the personal risks involved in manipulating events. His discovery—a functioning time machine—may hold the answers, but it also raises new uncertainties. Benjamin “Bunker” Kronovic, an aging actor with more regrets than roles, and Abigail Canaani, a reclusive librarian with a precise mind, find themselves unexpectedly at the center of the investigation.

Their search leads them through Brand’s early friendships, complicated histories, and layers of secrecy that suggest the past was never as fixed as it seemed. As they confront the possibilities Brand created, they must distinguish between coincidence, design, and the treacherous flexibility of time. The result is a mystery that unfolds with suspense and a steadily deepening sense of unease.

l I absolutely loved this book in so many unexpected ways. I admit, I was a bit surprised that the multiple threads that show up in chapter one without very clear delineation were easy to follow. Normally, something like that would fall under my pet peeves list, but the way Blum handles it, makes it obvious, even when the transition isn’t super clear. There were a few things that struck me from the start, like how much like Sherlock Holmes “Bunker” seemed from the very start. The first chapter, and our introduction to Bunker especially, had me so hooked that I was reluctant to stop reading once I started, even though this isn’t a short read. If you enjoy Sherlock Holmes style mysteries, mixed with a bit of sci-fi/speculative fiction, then you’re going to love this!
