There seems to be a new trend in biography. An author takes a deep "core sample" of the entirety of the world around the biography's subject, often even injecting his or her personal experiences researching and writing the book. Weather, stock tables, the history of minstrel shows or solid state engineering or cooking can weave in and out amidst unexpected finds at flea markets and wars.
A bellwether of this kind of tome, for this reviewer at least, was David Hajdu's magisterial Ten Cent Plague, a history of the comic books that could be an x-ray of American art and politics of our time. Yunte Huang's new, essential tome about Charlie Chan is a thrilling addition to this trend.
