If you were talking about different plotlines, truely there were five of them:

1. Krauss wanted to cover up Kinzo's death, his accomplices are Natsuhi, Nanjo, one-winged eagle servants and Kumasawa (concerning her nosy character, it was unlikely she could not have discovered it) and Gohda (he should not know about Kinzo's death, but he was trusted by Krauss and Natsuhi.

2. Eva, Hideyoshi, Rudolf and Rosa plotting to extort money from Krauss. They do not care much about the Ushiromiya family but rather their own immediate families. Except Eva, the other three did not care about the who got the title of head of Ushiromiya family.

3. Real Beatrice: the one who wrote the letters and gave them to Maria, the one who urged the whole family to solve the epigraph before the typhoon ended.

4. Murderer Beatrice (could be (and should be) the same as the 3rd one): Who planned and murdered 17 people on Rokkenjima according to the epigraph. The ultimate beneficiary was Sumadera family. She was also the one who wrote the letters-in-the-bottle, sent the bank cards, and being Maria's master.

5. Kinzo: the intention of the epigraph, his wills. His own plan determined the action of the one-winged eagle servants.
