For the past two years, however, Dr Qiu Xiangguo has been receiving a different kind of scrutiny, after being escorted off the Winnipeg, Manitoba lab premises with her biologist husband, Dr Cheng Keding, for security reasons.

Exactly why the scientists were ejected from the lab in 2019 was a mystery.

But snowballing speculation turned into an avalanche after the Covid-19 pandemic broke out a few months later, with elements of their situation seemingly tailor-made for these times of high tension between Beijing and the West.

These include the couple’s Chinese origins, a Royal Canadian Mounted Police investigation into possible policy breaches at the lab, and that Qiu sent live viruses to the Wuhan Institute of Virology four months before her ouster.
