Letting the reader learn everything about the muder -- the why, who, and how -- in the first couple of chapters isn't new. Yasuko and her daughter, Misato, killed the husband/father. Then, their neighbor, Ishigami, calls and offers to help them bury the body.
How'd he know?
Well, it's Ishigami’s brilliant cover-up that drives the story forward! OMGosh! Brilliant writing!
Anyway, Detective Kusanagi of the Edogawa police and his friend, Yukawa, a friend and a genius who sometimes helps the police, battle to find the truth surrounding Togashi’s murder.
The truth they try to prove is that Yasuko's story is a lie.
We readers see fragments of Ishigami’s plan... At first it seems simplistic; even sort of careless. However, we discover all too soon it's actually quite a deceptive plan and it's pretty complex.
Oh, yeah, Ishigami is a mathematical genius and he's a logical thinker and even tells mother and daughter that logic will get them through everything... yes, he actually applies math ideas to their problem like in that TV series "Numb3rs".
I totally, 110% recommend this book to those who love mysteries.
