Half-Blood Blues (styled without the hyphen in the UK edition) is a fiction novel by Canadian writer Esi Edugyan, and first published in June 2011 by Serpent’s Tail.

Griffiths' friend and bandmate, Hieronymus "Hiero" Falk, is caught on the wrong side of 1939 Nazi ideology and is essentially lost to history.

Racial hatred is in vogue, and a mixed-race German citizen (dubbed by the Nazis with the epithet "Rhineland Bastard") like Hiero Falk can be arrested and simply disappear, lost to history.

Watching their life on the big screen turns out to be somewhat different from what they expected, and the mysterious letter that Chip has received leads them to another journey, across countries, time, and their own emotions.

"[3] Donna Bailey Nurse in a review for The Globe and Mail said Half-Blood Blues "can be compared to a jazz symphony with discrete movements, shifting moods and a complex chorus of human and instrumental voice", and concluded by describing it as a "brilliantly conceived, gorgeously executed novel.
