Don't Call it Mystery (Omnibus) Vol. 3-4

A CURSED INHERITANCEWhen Totonou goes to Hiroshima, his only goal is to finally see an art exhibit (and maybe run into his fugitive best friend). But instead, Totonou gets dragged into a battle of wits. Kariatsumari Shioji is a teenage girl who needs his help. Shioji and her cousins have been named as beneficiaries in their grandfather-s will, but they-ll only receive their share if they can solve a cryptic puzzle. If that wasn-t enough, Shioji suspects that her cousins are willing to kill in order to win. After all, last time there was an inheritance battle in the family, a whole generation ended up getting wiped out. Can Totonou unravel the mystery before there-s another bloodbath?
