Karlheinz Schreiber wrapped up his fourth day of testimony in front of the Ethics committee today.

But it may not be his last.

He has given the committee all sorts of document, tips and ideas on who to call in front of the committee next.

The committee is plodding through it all, but is still having a hard time understanding it and that's not surprising.

The events Schreiber describes date back decades and while many of them lead back to him; they're all awfully different. From light armoured vehicles, to airplanes to German reunification to the ins and outs of the world of lobbying: it's enough to exhaust anyone. Or, at very least, to require a detailed flow chart with pictures of key people.

Say, that's not a bad idea!

Schreiber was in fine form again today. He always seems happy to be in front of the committee. Since being released on bail Schreiber seems more prepared (although for some reason he always wrongly refers to the Prime Minister's house as 26 Sussex and not 24), has got a haircut and arrives with his documents neatly organized in a large (and undoubtedly pricey) Louis Vuitton bag.

Schreiber may get a break over the holidays, but he will likely be listening closely this Thursday; that's when the other key witness finally gets his say.

Brian Mulroney will testify for four hours this week. And while Schreiber says he doesn't care what Mulroney says, it's hard to believe, if for no other reason than Schreiber is suing Mulroney to get back the 300-thousand dollars he gave to the former Prime Minister.

Schreiber says he doesn't hate Mulroney, but it's clear the friendship is over. He says, for him, when things get to a certain point, he cuts friends out and never goes back.

Schreiber, however, will be back: the questions aren't over yet.
