In 1910, Dr. Hawley Harvey Crippen poisoned his wife, Cora, and fled to Canada with his mistress in disguise. Detective Walter Dew, who cut his teeth on the force while hunting for the Ripper in 1888, donned a costume of his own as he pursued the fugitives. Like the Whitechapel murderer, Crippen is dubiously said to have procured his disguise from wigmaker and costume designer Willy Clarkson.
