A murder by a simple coffee poisoned seems very little to keep us in suspense over 200 pages. Think again, creating the immense ingenuity of Keigo Higashino is the sublime concealment of evidence, the apparent impossibility of the murder, the quest GRALE that this is the perfect murder.
Readers will delight in guessing and gradually discover the clues leading his investigation to another level as the police because its elements known him. Sublime.
I also note a very careful work in the development of the main characters, original without being caricatured and pleasant psychological depth. It is a pleasure to see the inspector and the physicist in complementarity after an investigation that I also recommend in "dedication suspect X". (It is not absolutely necessary to read these two novels in order of publication as investigations are completely independent).
However the author has chosen again to a novel based on facts, the concrete and that showcases the reflection putting a little aside moods, atmospheres and relationships which, incidentally, are very different from Western conventions and gives a special touch to the work.
Throughout the novel the end converges to an exceptional ingenuity.
A novel that I recommend to all lovers of crime fiction, since the Japanese in such little touches represented in rising sun really worth seeing.
