Seeking straight answers
The easy way to settle the question of why former director of immigration Laurence Leung Ming-yin took early and sudden retirement on July 5 last year might be to accept his own initial explanation.
Four days after the event, he told reporters he had stepped down because of mental exhaustion, partly provoked by the murder of his daughter in Canada two years earlier.
Looking 'frail and tired', as the South China Morning Post put it at the time, he insisted he had decided to go for 'personal, mainly health reasons'.
Offering acceptance and a little sympathy might be the easy way out. But it is not the way the Legislative Council Select Committee inquiring into his departure is likely to pursue the matter when Mr Leung appears before them on Friday.
His claim was not believed at the time, and has since been worn threadbare by the Government's determined, but counter-productive efforts to cover his tracks.
Whether Mr Leung's new testimony this week will take the investigation any further remains to be seen. But legislators are determined this is one sleeping dog that must not be allowed to lie.
Almost since the moment of his resignation there have been rumours about what lay behind it, some of them published in the press here and in Britain, others only the subject of barroom gossip.
