Zombies of the Gene Pool by Sharyn McCrumb
Originally published in March 2005, on my original 52 Books blog.
As a mystery, the book is not what one has come to expect of the genre: the death occurs more than halfway through the book, and is not revealed as a murder until 30 pages from the end, so the whodunnit part of the mystery is solved very quickly. The where-was-he-and -what-was-he-doing part takes a bit longer to solve. The identity of the murderer and the main twist will be obvious to most experienced mystery readers, the second twist is slightly more surprising (his motives), and the final one was transparent - at least to me - although I dare say it will surprise many less cynical readers.
The book is well written and funny, and I enjoyed it in spite of the long lead-up and the weak mystery. Looking forwards to reading the prequel, Bimbos of the Death Sun, which takes on sci-fi conventions. 3+ stars.
