James notes lots of gory similarities, but is not entirely convinced of the identification, since his killer, Paul Mueller, did not like cold weather (!) and because Nova Scotia was a long way away (Very American ideas about Canada, no?) The case was never solved, but the victims were bludgeoned with an axe while sleeping and then had their home burned down around them -- which was pretty much the standard Mueller method.
The CBC story on the unsolved murder also points out that the Nova Scotian detective and future Halifax police chief who unsuccessfully investigated the case has his own biography. but not an admiring one. Nova Scotia writer Bob Gordon makes the case that Nic Power would charge anyone with anything so long as it got good press coverage. His book, with the telling title The Bad Detective: The True Story of a Victorian Sleuth, will be available in May.
