But before that, voice actors read emails exchanges that took place between Barry, Honey and others that could show signs of a contentious household.     The Billionaire Murders podcast is probing the strange case of the famous Toronto couple found strangled in their north Toronto home in 2017. For seven years, The Star’s Kevin Donovan has covered the case for the Star, fought court battles to access documents on the police investigation and the Sherman estate, written a best selling book on it and produced a Crave documentary.
