Tokyo Damoi is a historical mystery linking the beheading of a lieutenant in a Siberian prisoner-of-war camp to the disappearance of a former internee in the present day. An unidentified body in Maizuru and a poetry collection recording events sixty years earlier lead the investigation toward truths buried in fading memory.

A murder in a camp sixty years ago and a disappearance in the present: memories left in frozen ground break a long silence.
