I am on a Michael Gruber Jag. I read Tanenbaum's Butch and Marlene Detective novels and enjoyed them years ago. When I found out Gruber wrote them I looked him up starting with the first of the JImmy (Iago) Paz novels. Loved It! I read the second book the got His "The Book of Air & Shadows" then The Good Son and now the third of the Trilogy. I may have to go back and read the Butch and Marlene series when I finish his more recent books. Luckily he has another book coming out soon.
