Japanese Police

On an unnamed island off an unnamed coast, objects are disappearing: first hats, then ribbons, birds, roses - until things become much more serious. Most of the island's inhabitants are oblivious to these changes, while those few imbued with the power to recall the lost objects live in fear of the draconian Memory Police, who are committed to ensuring that what has disappeared remains forgotten. When a young woman who is struggling to maintain her career as a novelist discovers that her editor is in danger from the Memory Police, she concocts a plan to hide him beneath her floorboards.

A decade ago, Tokyo Police Detective Kyoichiro Kaga went to collect the ashes of his recently deceased mother. Years before, she ran away from her husband and son without explanation or any further contact, leaving her estranged son with many unanswered questions. Now in Tokyo, Michiko Oshitani is found dead many miles from home. Strangled to death, left in the bare apartment rented under a false name by a man who has disappeared without a trace. Oshitani lived far away in Sendai, with no known connection to Tokyo—and neither her family nor friends have any idea why she would have gone there.

Detective Kyochiro Kaga of the Tokyo Police Department has just been transferred to a new precinct in the Nihonbashi area of Tokyo. Newly arrived, but with a great deal of experience, Kaga is promptly assigned to the team investigating the murder of a woman. But the more he investigates, the greater number of potential suspects emerges. It isn’t long before it seems nearly all the people living and working in the business district of Nihonbashi have a motive for murder.

Acclaimed best-selling novelist Kunihiko Hidaka is found brutally murdered in his home on the night before he’s planning to leave Japan and relocate to Vancouver. His body is found in his office, a locked room, within his locked house, by his wife and his best friend, both of whom have rock solid alibis. Or so it seems.

Newly reinstated to the homicide division and transferred to a precinct in Tokyo, Inspector Iwata is facing superiors who don't want him there and is assigned a recalcitrant partner, Noriko Sakai, who'd rather work with anyone else. After the previous detective working the case killed himself, Iwata and Sakai are assigned to investigate the slaughter of an entire family, a brutal murder with no clear motive or killer.

From the time she was a child, Mas Arai’s daughter, Mari, was completely gasa-gasa - never sitting still, always on the go, getting into everything. And Mas, busy tending lawns, gambling, and struggling to put his Hiroshima past behind him, never had much time for the family he was trying to support. For years now, his resentful daughter has lived a continent away in New York City and had a life he knew little about. But an anxious phone call from Mari asking for his help plunges the usually obstinate Mas into a series of startling situations.

Few things get Mas more excited than gambling, so when he hears about a $500,000 win - from a novelty slot machine! - he’s torn between admiration and derision. But the stakes are quickly raised when the winner, a friend of Mas’s pal G. I. Hasuike, is found stabbed to death just days later. The last thing Mas wants to do is stick his nose in someone else’s business, but at G. I.’s prodding, he reluctantly agrees to follow the trail of a battered snakeskin shamisen (a traditional Okinawan musical instrument) left at the scene of the crime.

After a brutal murder investigation ripped apart his life, Kosuke Iwata quit both his job as a detective with the Tokyo Police Department and his country, leaving Japan for the hopefully sunnier shores of Los Angeles, California. Iwata sets up shop as a private investigator. Approached by an old contact whose daughter has been murdered and the case laid to rest - unsolved - Iwata agrees to take on the case out of loyalty. But what seems initially like a cold-blooded murder takes a different turn when a homeless witness recalls the murderer’s parting words: “I’m sorry.”
