The more pressure is put on scientists to publish in scientific journals, or else to perish, the less likely it gets that an excellent popular science book like A Fly for the Prosecution is written. Being one of the old masters of forensic entomology -- that is, the science of determining post mortem intervals, and many other issues related to mostly violent death --, Lee Goff leads us through his exciting and at the same time entertaining world that strongly depends on silent crime scene assistants: maggots, adult flies and beetles, and once in a while a grasshopper, too. Many of these animals are attracted to decomposing body tissue. Their growth rate, and their succession are predictable, and can therfore be used to estimate the time when they started to feed on a corpse, or the time they got attracted to the body for other reasons like predating maggots, or building breeding chambers.
