Endless Night

A novel that unfolds from the first-person perspective of Michael Rogers. The reader empathizes with the protagonist Michael until the last moment and sees the world through his eyes.
Therefore, it provides an even more shocking twist when the truth is revealed and causes confusion in judgment.
The Murder of Roger Ackroyd has a similar development.

Personally, among works featuring such an unreliable narrator, I enjoyed reading Keigo Higashino's Malice the most.

This work is said to have been chosen by Agatha Christie herself as one of her most cherished works.
In this work, there is no great detective or complex alibi puzzle; it only doggedly follows the twisted inner self of a human, the perfect crime he designed, and the process of his own destruction.
