Chapter 3 - Entomology
This chapter on insects was way better than the others so far, although for some reason it was necessary to describe one of the entomologists as "a tall man who strides through the museum's galleries giving a cheerful and enthusiastic running commentary". At least his wardrobe wasn't described.
This chapter again discusses several cases where insect evidence was used but these seemed far more to the point and brought up for a specific purpose rather than just page filler. We even start off by learning that entomological evidence was used back in the 13th century in China and that a Chinese official wrote a handbook for coroners that was still in use hundreds of years later.
