The Milky Series: "If You Look Back, You're a Detective" and "Yo-i Don! Detective." I found these books on the bookshelf. There's a little wear on the top and bottom of the covers, but no writing or markings. I haven't had anyone to read them, so I've put them away. I hope someone will read them. #MilkySeries #IfYouLookBackYoureADetective #Yo-iDonDetective #RyoSugiyama
