Fujita is arrested on suspicion of selling a fake Albrecht Dürer painting as real and so Mitamura is called as an expert witness and appraiser by the police. Although initially she believes the painting is a fake, a greeting card from Fujita with a copy of Kouhaku Hasegawa's ink painting "Shourinzu Byoubu" causes her to conduct further investigation and analysis. Finally, in court, she appraises the painting as a genuine Dürer, but possibly unfinished and signed with his unique monogram later after it was varnished. Fujita later meets Mitamura at Tokyo National Museum before the original six-panel painting of "Shourinzu Byoubu" and thanks her, although she still threatens to expose him as a charlatan.
突然、逮捕されるフジタ。罪状は詐欺容疑。デューラーの贋作を真作と偽り、五億で売りつけられたと、買い手が訴えたのだ。しかし、刑事の厳しい取調べに対しても、あくまでペースを崩さないフジタ。そこで、検察側が用意した証人。それは、何と三田村。彼女は、デューラーの真贋を判定すべく、選ばれたのだった。
