Aoi mostly sits this one out, with her brief appearances book-ending the episode. Instead, it’s Akihito accompanying Holmes on his latest mission, with the added objective of giving the actor some pointers for a Kyoto-based TV role. Despite Holmes still being weary of Akihito, he does admit his true nature regarding women (he’s through with long/deep relationships, but would be open to flings).
In another example of the “culprit” showing their face almost immediately, the monk Ensho is their guide as they tour Nanzenji Temple, which is full of several magnificent works of art…and one that is merely “impressive.” Holmes’ suspicions about the scroll in the entryway are confirmed when the vice abbot informs him that Nanzenji’s “dragon” has indeed been stolen as the note indicates. To be more precise, it was swapped.
It turns out Ensho is the forger, and he’s a very good one, but not good enough to get past Holmes. While Holmes didn’t sense the “malice” and desire to deceive in the fake dragon scroll, it still lacked the aura of the genuine article, and Ensho was walking, talking, and breathing strangely when the scroll caught Holmes’ attention. And make no mistake; while the fake was impressive, Holmes does not consider it art; he’s even pissed enough about it to lapse into his drawl.
There’s likely a part of Ensho that’s glad he was acknowledged, but he’s determined to evade Holmes’ sharp appraising eye, as well as justice. Since he has shinobi training, he won’t be easily caught, but in the meantime Holmes can commit himself to exposing every fake work of art Ensho tries to pass off as real. Now that he knows so much about the forger, his task shouldn’t be beyond his abilities.
