Trent's Last Case, published when Conan Doyle and Chesterton were both at the pinnacle of their respective literary careers, was the first detective story to use fingerprinting as a means of detecting the criminal. Dedicated to his friend G. K. Chesterton, E. C. Bentley, a journalist first with the “Daily News” and then with “The Daily Telegraph”, intended the book to be a gentle parody of the detective genre, only for it to be quickly hailed as a classic.
