In a world in which we're conditioned to disregard nuance in favour of labels which denote good, bad and little else, Marie-Andrée Leclerc poses a problem.
The medical secretary from Quebec, Canada met Charles Sobhraj in 1975 on her travels in India and became enmeshed in his web of deception and murder.
If you had asked her if she was capable of not only tolerating such monstrosities but performing an active role in them before her path crossed with that of Sobhraj's, Leclerc would, in all likelihood, have been appalled at such a question.
But she did, only stopping when forced to by the authorities.
