Today two "behind the scenes" witnesses will appear in front of the House of Commons ethics committee's investigation into the dealings between Karlheinz Schreiber and Brian Mulroney.

Luc Lavoie is first up to bat. Best known to most for his deep voice and staunch defense of Mulroney for years and years, Lavoie was Mulroney's spokesperson up until December. He left saying he no longer had time for it.

It was Lavoie who was sent out to handle this whole affair the first time round in 1999. When Fifth Estate producer Harvey Cashore spoke to Lavoie about some of what he was investigating, Lavoie said there had been no exchange of money between Schreiber and Mulroney. He also, rather famously, said, "Karlheinz Schreiber is the biggest (insert expletive here) liar the world has ever seen."

Of course, as it turns out the former prime minister did accept money from Schreiber.

This time Lavoie will be here to speak for himself and himself alone.

Next up: Francois Martin, the Mulroney's chef for years at 24 Sussex. In the past Martin has talked about dropping off and picking up big envelopes of money for the Mulroneys. He has said that what he saw was "disgusting."

The money, Mulroney's people have said, was from the PC Canada Fund and was essentially to cover Mulroney's expenses as Prime Minister, but Martin's testimony will likely give a glimpse into the kind of life the Mulroney's were living while in office.

Stay tuned.
