Sherlock Holmes meets Perry Mason meets SCI. Interesting rip off of the Sherlock Holmes genre. Since Freeman wrote the Thorndyke mysteries while Arthur Conan Doyle still churned out Holmes mysteries, the derivative nature of his stories would have been that much more obvious to readers.
Unlike Holmes, Thorndyke is presented as a medical doctor and scientific mind, but many of the trappings of the tale parallel Holmes stories including the dense biographer. This particular volume is additionally burdened with a soporific court scene.
That said, the scientific background for this 1907 story, including its critique of the uncorroborated use of figure prints, will entertain modern readers.
An interesting read.
