Tuesday: Detained Canadians, soccer grass lawsuit, narcissism study, and more...

According to Chinese authorities, a Canadian couple who run a coffee shop in Dandong may be spies -- but their son says there are no grounds for them to be detained...Men played the FIFA World Cup on nothing but real grass, which is why top women players are furious that their World Cup will be played on artificial turf...and one simple question can determine whether you're a narcissist -- and might be cause for rare self-reflection that doesn't involve three carefully angled mirrors.

Part One

Detained Canadians: son
Their family says they're just Canadian coffee shop owners. But the Chinese government says Kevin and Julia Garratt are guilty of stealing military and intelligence information, and endangering national security.

Botched execution file
The term "botched execution" is imprecise, and can suggest that the errors involved were pretty minor. In the case of the execution of murderer Joseph Wood, though, "botched" doesn't begin to cover it. The full report on his torturous death has been released -- and tonight, one of his lawyers takes us through his client's final hours.

Narcissism study
Narcissists believe they're great at everything. And while that's not necessarily true, they do turn out to be the absolute best at one thing in particular -- and that's knowing they're narcissists. How the self-absorbed self-identify, on tonight's show.

Part Two

Soccer grass lawsuit
A group of elite female soccer players is threatening legal action against FIFA, after learning that the turf to be used for next year's Women's World Cup is artificial -- unlike the real grass used for the men's pitches.

Nova Scotia pulp mill
The smell of success was never sweet in Pictou, Nova Scotia -- but now, the fight over the putrid emissions from a local pulp mill has turned distinctly sour.
