Aaron's Wait - An Elliott Smith Mystery, #2

Aaron Stiles is dead. He's been dead for four years but doesn't seem to know it. He's waiting for his partner Bill to come home, and until that happens, he's not going anywhere. The trouble is, Bill Somers won't be coming home-ever-because he's dead, too. The official verdict was suicide, but. The last thing Elliott Smith needs in his latest renovation project is a ghost, especially one who won't let him sell the place until he solves the mystery of who killed Bill.
Elliott has John to help with the spectral side of things, but that leaves Elliott with the quandary of how to get information on the case. After all, he can hardly explain he's investigating on behalf of one dead man with the assistance of another.
