Good Intentions, by Michael Z. Lewin

"Good Intentions," by Michael Z. Lewin, in Ellery Queen's Mystery Magazine,  November 2012.

Last year in this space I reviewed "Who Am I," in which Lewin gave Albert Samson, his Indianapolis private eye an unusual client: a quiet, unremarkable man called LeBron James who was convinced his father was an extraterrestial.

The would-be alien is back, this time calling himself Wolfgang Mozart.  He is still doing good deeds and for his troubles this time he gets stabbed.  Since he is unable to answer questions Samson has to figure out what happened and why. 

Mozart and Samson are sympathetic characters and the story is well-written.  (My favorite line: A nurse named Matty meets Albert's kid the cop.

"And she's YOUR daughter?"  Matty tilted her head.  "Your mother must be very very beautiful."
