This wonderful review was just posted on Goodreads, with 5 stars:
The book is every bit the equal of the fascinating story behind it. Written 40 years ago and left virtually untouched for decades, Death at the Flea Circus is a yarn one part dirty Brautigan, one part Sherlock Holmes procedural, and one part surreal, comic, almost Sci-Fi time-travel. Or maybe it’s just that, like the dusty manuscript forgotten in a drawer, the story doesn’t concern itself deeply with chronology. Or narrative, necessarily. The exacting and wildly inventive language of Brautigan is prominent here–not as a nostalgic tribute, but rather elbow to elbow as a contemporary; and the story belongs very much to the experimental schools made popular in the decades since it was written. What we end up with is a book wholly of another era, and yet timeless in the way that all fine writing is–a book that teaches us that the journey is the destination.
