The Devotion of Suspect X: A Detective Galileo Novel - Keigo Higashino, Alexander O. Smith
Yasuko divorced her abusive ex-husband, but that hasn't stopped him from finding out where she's living, and harassing her and her teenaged daughter. One night he ends up dead on Yusuko's apartment floor. Their neighbour knows what they've done and quickly devises a plan to cover up what really happened.

The characters are well developed and believable, and the story is full of twists and turns that will shock you. This book was amazing.
