Usagi Yojimbo Vol. 3 #90

Plot

Shortly after escaping their enslavement at the territory's edge, Usagi and the Geishu bodyguard Tomoe return to Lord Noriyuki's castle only to be greeted by a savage murder. The victim was a member of a trade delegation sent by Lord Kojima, and all evidence implicates a maid who died ten years ago! Unless Tomoe and the long-eared ronin can solve this mystery, treaty negotiations will dissolve completely and another throat may be clawed out.
