The Victorian sleuth 'Paddington' Pollaky was a contradiction: a man of mystery who craved the limelight; a meddling busybody whose heart was in the right place. This first-ever biography investigates his involvement in the American Civil War, his campaign against sex trafficking and his dogged search for abducted children. It examines his methods – including placing cryptic messages in The Times – and considers whether he was the inspiration for Sherlock Holmes or Hercule Poirot.
