The Honjin Murders by Seishi Yokomizo

In the winter of 1937, the village of Okamura is abuzz with excitement over the forthcoming wedding of a son of the grand Ichiyanagi family. But amid the gossip over the approaching festivities, there is also a worrying rumour - it seems a sinister masked man has been asking questions about the Ichiyanagis around the village. Then, on the night of the wedding, the Ichiyanagi family are woken by a terrible scream, followed by the sound of eerie music - death has come to Okamura, leaving no trace but a bloody samurai sword, thrust into the pristine snow outside the house. The murder seems impossible, but amateur detective Kosuke Kindaichi is determined to get to the bottom of it.
