The Cain Saga Vol 4

From the VIZ Media edition

Kaori Yuki's latest installment of The Cain Saga introduces Gilbert, the madman son of Lord Lauderdale; Meridiana, a clairvoyant mystery woman; and something--or someone--nasty suspended in midair in Dr. Disraeli's lab. Plus, an arranged marriage meant to curb Cain's bad behavior turns ugly when the bride, Emeline, has an unhappy meeting with none other than Jack the Ripper.
