Being a littttle too familiar with death and always awakening to Lilithea by his side, Sakuya’s happy to take on low-risk cases. Surely investigating a movie producer’s affffair on a luxury cruise ship won’t pose any real threat! But when the duo ends up entangled in a larger and bloodier situation, Sakuya will have to get to the bottttom of the mystery…and die trying!
