Where are Honey and Barry Sherman? It’s a typical day for these eccentric billionaires but they’re not answering the phone. After a gruesome discovery, the Sherman children decide to tear down the mansion where they grew up. Before wreckers arrive, a mysterious intruder discovers signs of an investigation gone wrong. This is episode one of “The Billionaire Murders: The hunt for the killers of Honey and Barry Sherman,” a “Suspicion” podcast probing the strange case of the famous Toronto couple who were found strangled in their north Toronto home in 2017. For five years, Kevin Donovan has covered the case for the Star, fought court battles to access documents on the police investigation and the Shermans and their estate, and wrote a book about it.
