Last December, a Canadian pharmaceuticals executive and his wife were strangled in their home.

No one knows who did it or why, but everyone has a theory.

The Scene Of The Crime

Last Dec. 15, two real estate agents arrived at a sprawling modern house near the northern edge of Toronto. They were accompanied by a couple who were considering buying the 12,000-square-foot mansion at 50 Old Colony Rd., recently listed for just shy of C$7 million. With five bedrooms, nine bathrooms, a gym, a sauna, a tennis court, and underground parking for six cars, it was one of the more impressive properties on a street lined with grand homes. The sellers, pharmaceuticals billionaire Barry Sherman, 75, and his wife, Honey, 70, had lived there for more than two decades but were preparing to build a house closer to the center of the city.

The Shermans weren’t supposed to be home that day. It was midmorning, and a housekeeper was doing her semiweekly cleaning while another woman watered the plants. The tour took in the hexagonal entrance foyer, with its chandelier and black tile floors, and the spacious kitchen, soaked in natural light from a broad conservatory window over the sink. In the basement, the Shermans’ agent had something more unusual to show off: a lap pool and hot tub, handy in a city where winter weather can drag into April.
