Sam is a talented composer, but he's not a very good pianist. As luck would have it, his brother Humphrey is a piano prodigy, and he gets all the attention in their family. However, people appear to be less interested in Humphrey now that he's in his mid-teens and no longer a cute child prodigy, so their mother cracks a scheme to get the audiences coming back: She will make Sam compose new pieces in the style of a long-dead composer and have Humphrey perform them, billing them as found works being channeled by the actual artist. Unfortunately, the fiction may be running away with the head and the hands of this operation. . . .
I really liked Sam as a character--as a musical person, I related to his love for musical creation, and appreciated his resentment at not being able to perform as well as his brother. The "hey, let's pretend a ghost is sending us new musical pieces" plot is a little scary for a mother to come up with just to sell tickets, but while she's not an incredibly believable character, the root of her behavior is all too real in the world of stage mothers. The incredibly spooky concept of a ghost reaching out to the brothers to dictate and perform new work was well handled.
