I've read many books, but I have only finished one. I usually don't have enough patience to finish the entire story... I prefer 映画 more.
Anywho, it's a Dutch book titled 'Verdriet' (that's 'Sorrow' in English). It's about a man and a woman who ロスト their son, who drowned in a swimming pool. Later in the story, they begin suspecting each other for murder.
It's very thrilling, so much even that I actually finished it!
