ガリレオの苦悩 (Garireo no kunou, The Anguish of Galileo, 2008) is a collection of five detective stories by HIGASHINO Keigo (東野圭吾). Higashino is best known in the west for The Devotion of Suspect X; and these stories are the third collection from the same series, featuring the genius physics professor, YUKAWA Manabu (湯川学), who is consulted by his friend KUSANAGI (草薙), a police detective, and Kusanagi's younger colleague, UTSUMI (内海). I've read two novels in the series and the second collection of short stories,予知夢 (Yochimu, Prophetic Dream, 2000). Utsumi is a new character, who also appears as the main character in the television series Detective Galileo, which started in 2007. In the books the police role is divided fairly evenly between Kusanagi, experienced but stubborn, and Utsumi, who is shown in the typical role in police stories as a woman policeman who has to fight to get her view of the case recognised.
In 予知夢 Yukawa's role was more or less that of armchair (or laboratory) detective, as I remember. (It's several years since I read it, before I started this blog; if you're curious, there's a review here). In these stories, following the model of The Devotion of Suspect X, there is often a more personal and active involvement.
Ochiru (Fall): a woman falls from the balcony of her appartment. It looks like suicide; but Utsumi comes to suspect that one witness is hiding the fact that he was involved with the victim. The witness though has a perfect alibi. He was walking just below the apartment when the victim fell.
Ayatsuru (Manipulate): Yukawa is invited to a dinner by a retired physics lecturer along with other former students. The old man, more or less limited to a wheelchair, lives with his illegitimate daughter. His estranged son by an earlier marriage has also recently moved in and is staying, an unpleasant and unwelcome guest, in a little house in the grounds. If you're familiar with the conventions of the detective story, you'll know that staying in a place like that is basically signing your own death warrant. So it's no surprise when the son is murdered while the guests are gathered together. The daughter was with them, but her father had been taking a rest alone. Still, in his condition he could not possibly have committed the murder.
Tojiru (Close): Higashino uses deliberately unconventional kanji for these stories. The one's used here are actually those for 'Locked Room'; and this is indeed a locked room mystery. Yukawa is invited by a friend to his inn in the mountains. A guest had died mysteriously, either by suicide or accident it seems, falling into a ravine not far from the inn. The locked room is not where he was killed, but the room where he was staying. Before his death was discovered the innkeeper had been puzzled when the guest did not appear for dinner and had looked at his room and found it locked from the inside; but he had had a strong feeling that there was actually nobody in the room. Yukawa is invited to solve this puzzle; but despite inviting him, the friend seems strangely unwilling to cooperate with the investigation.
Shimesu (Show): Utsumi is watching the daughter of a woman suspected of murder. When they see her finding the (now dead) dog that had gone missing from the victim's house, she claims to have discovered it by dowsing. Utsumi is unwilling to believe that she is lying. She had observed the girl using her necklace for divination as she followed her; but is such a thing possible?
Midasu (Throw into Confusion): a serial killer is taunting the police with his claimed undetectable murder method; and he has a particular interest in Yukawa.
These are all competent stories, but not especially interesting. The idea of a locked room mystery without a victim in it is a nice one though.
