Sherlock Bones Vol.4 by Yumi Ando and Yuki Sato

I started reading the Sherlock Bones series a few years ago, and had a little break inbetween Vol.3 and Vol.4, which is a shame because it ended in the middle of a mystery!  Sherlock Bones is a tiny, adorable, dog who is really the reincarnation of Sherlock Holmes…when he puts his pipe in his mouth he can talk to his ‘owner’ Takeru and solve crimes.
