Criminal Investigation: a Practical Handbook for Magistrates, Police Officers and Lawyers, Volume 3 by Hans Gross (1847 - 1915)

Reputedly inspired by the Sherlock Holmes stories, Austrian criminal jurist and examining magistrate Hans Gross wrote the first handbook on criminal investigation. This treatise covers everything from the qualities of a good investigating officer and how to utilize various experts, to tactics employed by criminals, how to analyze footprints and blood stains, and ways that criminals perpetrate crimes. Some of the remarks relate directly to India, such as disguising one's caste.
