There are many mystery/suspense manga that allow you to enjoy a harrowing story that you do not know how it will unfold. Here are three that I recommend.
1. MONSTER
Title : Monster
Written by : Naoki Urasawa
Published by : Shogakukan
Magazine : Big Comic Original
Original run : 1994 – 2001
Volumes : 18
Set in Germany after the fall of the Berlin Wall, this masterpiece of mystery manga exposes the human sins hidden in the darkness of history.
2. Erased
Title : Erased
Written by : Kei Sanbe
Published by : Kadokawa Shoten
Magazine : Young Ace
Original run : 2012 – 2016
Volumes : 8
This is a mystery manga centered around a murder case with the science fiction element of time travel. The well thought-out storyline and carefully drawn settings make it easy to understand without being complicated, despite the time travel involved.
3. Death Note
Title : Death Note
Written by : Tsugumi Ohba
Illustrated by : Takeshi Obata
Published by : Shueisha
Magazine : Weekly Shōnen Jump
Original run : 2003 – 2006
Volumes : 12
The Death Note brings death to the person whose name is written on it. The story that develops into a fierce psychological battle with such a simple setting is brilliant. It makes the reader rethink the definition of good and evil.
