Louis Berard: 2 books

Count Frederick von Waldberg, who was tried and guillotined at Paris under the name of Prado, was born at Berlin in 1849 and was named after King Frederick William IV. of Prussia, who, together with Queen Elizabeth, was present at the christening and acted as sponsor. This somewhat exceptional distinction...

A criminal known as "Pardo", who terrorized police departments throughout the 1880's, is arrested and held for a crime he didn't commit, and was never tried for the outlandish crimes he did commit.  Fascinating, gory tale.
